(macOS High Sierra’s initial install screen.) We’re always grateful that new versions of the operating system go through an extensive beta process, but it always seems a few issues will still be lurking, ready to pop up and surprise us. With that in mind, here are some of the more common problems you may encounter when upgrading to macOS High Sierra. Note: Before upgrading to any new or updated operating system, it’s a good idea to have a. Upgrading From the Beta If you’re a beta tester, you may have a slightly more difficult time upgrading than the rest of us; it all depends on whether you installed during the beta testing. Apple backed away from its original goal of having APFS ready to go for all Mac configurations. Instead, it’s releasing macOS High Sierra with APFS only for Macs using SSDs (Solid State Drives). If you converted a Fusion drive during the beta, it needs to be reverted to HFS+ before you can install macOS High Sierra.
Re changing from High Sierra back to Sierra: There are a number of sites that provide you with that info, but I've done this before with (previous OS versions) for others and it can be quite painful and time consuming.
Unfortunately, Apple isn’t providing any tools to revert the file system. Instead, you’re required to back up your current data with, erase and reformat the affected drive(s), install macOS High Sierra, and then migrate your backed up data to the fresh install.
Apple includes instructions for the process, specifically using Time Machine as the backup app. It seems you should also be able to perform this task by creating a clone using Carbon Copy Cloner or one of the other popular cloning tools. Nevertheless, even if you decide to create a clone, we highly recommend you also create a Time Machine backup, especially if the clone is the only copy of your data you will have. You’ll need a drive partitioned as HFS+ for the Time Machine backup.
This can be an existing Time Machine drive as long as it’s formatted as HFS+. You’ll also need to create a bootable macOS High Sierra installer; a 16 GB or larger USB flash drive or an external drive can serve this purpose. Warning: The process of creating the bootable installer will erase the contents of the selected drive volume. Apple has posted instructions in its support area for. It covers two methods for converting a Fusion Drive back to HFS+ and installing macOS High Sierra. The instructions are a bit sparse, but should be sufficient for getting the job done.
If you have any questions regarding the process, be sure to post them in the Comments section below. Downloading macOS High Sierra From the Mac App Store Stalls The process of should be an easy one, but a few of us have run into a problem where the download seems to fail to start, or freezes if it does begin. (If your download of macOS High Sierra seems to stall you may need to restart the Mac App Store.) In both cases, patience may be the best course of action.
But if after a reasonable amount of time, say 15 minutes to half an hour, there’s been no change, then it’s time for action. Open your web browser to any page; the idea is just to verify that your Internet connection is working. If you’re having network issues, they need to be addressed before continuing. Quit the Mac App Store. If it fails to respond to the quit command, force quit by selecting Force Quit from the Apple menu. In the Force Quit Applications window that opens, select App Store, and then click the Force Quit button.
You’ll be asked if you really want to force quit the App Store; click the Force Quit button. Once the Mac App Store finally quits, go ahead and restart the store. Select macOS High Sierra and start the download again. If you still have problems, quit the Mac App Store (using force quit, if needed), and then restart your Mac. Return to the Mac App Store and try again. Freeze During Installation After you start the macOS High Sierra installation process, you may notice that your Mac’s screen has gone black, and nothing seems to be happening.
The likely culprit is that your Mac has frozen during the restart process. The installation process copies needed files to the destination drive, including a minimum boot environment.
Once everything is in place, your Mac should restart and finish the install process. If you’re stuck at the black screen, you should wait for a reasonable amount of time; no more than half an hour.
If your Mac doesn’t finish the restart by then, go ahead and manually shut your Mac down by pressing and holding the power button. (The installation of macOS High Sierra can stall on a totally black screen, or one with the status bar showing. Either way, be patient before forcing a restart.) Once your Mac has shut down, you can restart it.
Chances are your Mac will restart and pick up by displaying the Setup Assistant, ready to finish the install process. If you still find yourself stuck, try shutting down again, but this time. Once the desktop shows up, as well as any anti-virus apps you may have, and then restart your Mac. You’ll need to restart the macOS High Sierra installation process again.
If you’re still unable to resolve the problem, try and using the Disk Utility option to check and repair your startup drive. Once your drive has a clean bill of health, use the Reinstall macOS option to ensure the startup drive’s operating system is intact. Once you return to the desktop, you can restart the install process. Slow Performance After Install Some temporary performance issues can be attributed to spotlight indexing that may be running; after all, there’s a lot of new data on the drive that needs to be catalogued.
Time Machine can also become active soon after an install and slow things down a bit. Waiting a short time will likely see the slowness clear itself up with no intervention on your part.
Should the slowness continue, you can try the tips outlined in. Wi-Fi Issues When macOS Sierra was released we saw quite a few Wi-Fi-related issues, which we address in the guide:. Thankfully, at least so far, we’re not seeing a repeat of major Wi-Fi issues.

But that’s not to say there aren’t at least a few of them. During the beta, there was a recurring problem with connecting to a personal hotspot, such as one provided by an iPhone. The solution was simple enough: just turn Wi-Fi off and back on again, the ultimate IT solution for most problems. (Turning Wi-Fi off and then on again can restore a connection that doesn’t work after installing High Sierra.) To turn Wi-Fi off, select Turn Wi-Fi Off from the Wi-Fi status icon in the menu bar.
To turn Wi-Fi back on, select Turn Wi-Fi On from the Wi-Fi status icon. If you don’t see the Wi-Fi status icon in your menu bar, launch System Preferences from your Dock or Apple menu, and select the Network preference pane. Place a check mark in the Show Wi-Fi Status in Menu Bar box. Apps Not Working Unfortunately, it’s the nature of progress that some apps get left behind when operating systems are updated. If you have an app that has stopped working under macOS High Sierra, you should check with the developer to see if any updates have been released, or will be released. You can also check with, a site that gathers information about which apps work with what version of the Mac operating system.
(Sometimes an app may fail to complete launching, or behave strangely when a new version of the macOS is released.) If you believe the app that you’re having problems with should work with macOS High Sierra, you can try deleting the app’s cache files. Here’s how to do that: Quit the app in question, if it’s currently running. Open a Finder window or click on the desktop to ensure the Finder is the front most application. From the Finder’s Go menu, select Go to Folder. In the sheet that opens, enter the following: /Library/Caches From the Finder window that opens, find the folder whose title includes the name of the app you’re having issues with. Open the app’s cache folder, and delete any items within it., and then launch the app in question.
With any luck, the app should now be able to launch and work correctly. Additional Rocket Yard Reading.
Stay tuned for problems you might have installing the new macOS Mojave. I’m running a mid-2012 MacBook Pro with 8GB of RAM and 750GB HD still less than half-full.
I recently updated from Sierra to High Sierra without any immediately obvious problems. My usual software runs okay. But now it’s impossible to access the second user account used occasionally by my son.
Trying to log in with the same password sets up a rotating image which never ends, and since there is no way offered to step back from this situation, the only option is to restart the computer. I’ve tried changing the account from Standard to Admin and I’ve changed its password – after each change rebooting the computer (which has become very, very slow, by the way). Nothing helps and trying to log into the second account continues to lock up the computer completely.
Any suggestions how to remedy this situation? Thanks in advance for your suggestions. Same for me @ George smith, I upgraded to high sierra and I think they must have been ‘high’ when they made it because after a time or two booting my computer it went to black screen and had to get a new os put on unfortunately they put the same one back in because of miscommunication and it happened again! It’s really a shame but I’m stuck with El Capitan at the moment until I can work out if this bug has been fixed or not. I don’t want to risk shelling out more money because Apple have gone down the drain.
I can hardly believe Apple has become Microsoft – buggy, difficult to fix software, that leaves your machine hanging. It used to be that Mac just worked – straight out of the box with minimum initial configuration. Now I am plagued by problems from the get-go: my new MacBook Pro started with a black screen out of the box. It gave me only voice prompts that are normally only for visually impaired people. After I great struggle I set it up.
Then the upgrade to 10.13.4 could not complete on its own and forced me into reading multiple blogs with potential solutions posted by people who experienced the exact same problem. Finally, I managed to complete the upgrade. The the sleep issues started – if the machine goes to sleep for a long period of time (more than 2 hours), when you try to wake it, it just displays a black screen (the keyboard lights up and responds to command). This forces me to initiate a cold reboot every time. So, people from Apple, how long have been making computers and is this acceptable for the most expensive company in the world who prides itself on QUALITY!? My next laptop will be HP. You are fortunate that my company is paying for this machine, otherwise I would have long returned it to you.
I have an iMac 27″ mid-2010 on my bench right now that came in with a black screen problem on High Sierra. The machine is RUNNING, it just has a black screen.
Attaching an external display gets you a perfectly good screen. I ended up sapping the PRAM, and it fixed the problem. Then I booted it on an external pack I had that was running the same version of High Sierra. It worked fine until I tried to run the online updates for iTunes 12.8 and HS 10.13.6. Near the end of the iTunes update, the main screen went black again (in fact it’s in that state right now — I’m using the external display to type this). Curiously, when I got this Mac from the owner, only the 10.13.6 update was pending.
Now I’m wondering if it’s iTunes 12.8 that bricks the screen somehow. I guess I’ll know when this update completes.
I couldn’t even put my computer to sleep from the Apple menu after installing High Sierra a few days ago. It always logged me out instead and stayed awake.
Using Excel with it was another problem, and a lot of my Excel files were corrupted. Needles to say I rolled back my OS swiftly, but I thought I noticed inconsistent behavior when it came to asking for the master password before unlocking my Safari passwords. My computer is 2012 model and you think after the amount of time High Sierra has been out that I wouldn’t have such an obvious problem as not being able to sleep my computer from the Apple menu.

Advertisement Have you noticed sometimes that your Mac cursor jumps around all over the place? One minute you’re typing away and the next minute it’s highlighting random text or typing from somewhere completely unexpected. If you have this problem, you’ll know it’s a huge pain, because you find you spend more time fixing the errors it causes than actually getting on with the typing task at hand. For some of us, help is easy to find. Others, not quite so easy. This seems to be something that occurs due to a number of different causes. We’ll go through several causes and fixes for this and hopefully one of them will work for you.
This really is an annoying problem for Mac OS X users, as it makes typing practically impossible. Even when you’re very careful not to touch the trackpad, it seems to unexpectedly jump a few lines, highlight text, type over that highlighted text and randomly ruin your whole efforts to type. Sometimes it can seem as if you’re typing CMD-Z as often as you’re typing text. But don’t worry – you’re not alone and it can be fixed.
Ignore Accidental Trackpad Input The simplest fix is ensuring you’re not accidentally bumping your trackpad while you type. Go into Apple Menu System Preferences and check your trackpad settings. For Snow Leopard, there’s a “ Trackpad” section, while for earlier Mac OS X systems it will be under “ Mouse & Keyboard“. Open this and ensure that “ Ignore accidental trackpad input” is selected. For many users, this will sort the problem out for you in no time.
Ignore Trackpad When Mouse Is Present Connect a USB mouse and go into Apple Menu System Preferences Mouse preferences (or “ Mouse & Keyboard“). Set your system to “ Ignore trackpad when mouse is present“. Now hopefully whenever you’ve connected a mouse you should have no problems with erratic cursor movement. Check Your Laptop Is Still Flat Some older Macbooks can develop erratic trackpad behaviour when the laptop casing gets slightly twisted. This might be because of something habitual you do, such as carrying the laptop in the same position each day or resting it on your lap.
Rest it on a flat surface and press on one end to see if your laptop is still perfectly flat. If it’s not, take it in to an Apple shop and see if they will twist it back to flat for you. Don’t do this yourself if your laptop is still under warranty! Your Battery Might Be Failing Some users have reported that this erratic cursor movement is linked to battery failure on their laptop. To test if you’re in this boat, try removing the battery and running the laptop on power only.
If your cursor behaves nicely while the battery is out, you might want to consider replacing the battery on your laptop. Upgrade To Lion If all else fails, it’s possible that With OSX Lion in the App Store awaiting you, I’m sure some of you have some concerns about the upgrade process, so today I’m going to walk you through some of those concerns, give a.

More Mac Fixes While you’re fixing things, here’s a few more tricks and hacks you might find useful. Apple‘s upcoming OS Lion trackpad and mouse gestures don’t compare to what BetterTouchTool and another similar application, MagicPrefs, have to offer. These applications are for Mac users who find Apple‘s default click, tap, and two-finger. If you depend upon your Mac hardware for job related purposes, you should know how important it is to be prepared for unexpected problems when they occur.
