A lot of users are complaining about Safari, saying it’s causing freezing issues. By freezing, it is meant that your Mac is completely unresponsive.

It seems that Safari causes the entire macOS system to lock up.

You may be experiencing some of the following symptoms:

• Scrolling a webpage in Safari causes your Mac to freeze.
• The keyboard does not work.
• Forcibly rebooting your Mac is the only way to fix it.

We know that crashes and freezes in macOS are extremely rare however you may still find that your Mac has become unresponsive, and you may get very frustrated when your Mac isn’t doing what you expect.

Please try the tips below. Try each fix until your issue is fixed.

See this article if you cannot open Safari.

Before you do anything, make sure that your Mac is running the latest version of the macOS software. Here is how you can update your Mac:

• Click the Apple menu.
• Click System Preferences.
• Click Software Update. This will check for updates. If there is an update available, click the Update Now button and follow the onscreen instructions.

If you are using an earlier version of the macOS software (macOS High Sierra and earlier), you can update your Mac by going to the App Store app. And then click Updates.

Fix 1:

1. Force quit the unresponsive apps, e.g., Safari.
2. Apple menu > Force Quit.
3. Or press Option-Command (⌘)-Esc.
4. Then select the unresponsive apps and select quit.

Fix 2:

Check Safari extensions. Some extensions may cause issues. Here is how you can troubleshoot this problem:

1. Open Safari.
2. Click Safari and Preferences.
3. Click the Extensions tab.
4. Deselect the checkbox “Enable… extension.” Repeat this for all the extensions you have installed.
5. Now close the Safari and reopen it. Does this resolve your issue? If not, you can reenable the extensions. If so, then one of your extensions is causing this problem. You can reenable them individually until you find the extension that is causing the issue.

Fix 3:

You may want to delete Safari caches. Here is how:

• On your Mac, open Safari.
• Click Safari > Preferences.
• Click the Advanced tab.
• Select the “Show Develop menu in menu bar” checkbox.
• Now restart Safari.
• Then, in Safari, click Develop (menu bar).
• Select “Empty Caches”.

Fix 4:

1. Close Safari.
2. Open the Terminal app (Applications > Utilities > Terminal).
3. Enter the following command:
4. defaults write com.apple.Safari IncludeInternalDebugMenu 1
5. Then hit return (see below how you can disable the debug menu).
6. Now relaunch Safari.
7. You will see the Debug menu in Safari’s menubar.
8. Click Debug.
9. Select Drawing/Compositing Flags.
10. Choose “Disable Canvas Accelerated Drawing” and “Disable Full Page Accelerated Drawing”.
11. Now check to see if your problem is fixed.

Fix 5:

1. Restart your computer in Safe Mode. Here is how:
2. Turn off your Mac.
3. Now turn on your Mac.
4. Press and hold the Shift key the instant when you hear the startup chime.
5. Release the keys when you see the Apple logo or the login screen.
6. If Safe Boot resolves this issue, restart the Mac normally without pressing the Shift key.

You will have to relaunch Safari.

2-It seems that especially macOS Sierra users are facing this problem.

It’s almost become a tradition; one that we wish we didn’t have to put up with. It seems with each new version of the Mac operating system, there are some features that just don’t seem to work the way they used to. The tradition lives on with macOS High Sierra, so we’re gathering a list of what High Sierra broke and how to fix it (when you can).

Drive Encryption Can Change Formatting
Encrypting an entire drive to add a level of security has been an easy task in the Mac OS ever since FileVault 2 was released as part of OS X Lion. Full disk encryption has been a boon for Mac users who worry about their personal data being easily accessible on their Macs or external drives. This is especially true for portable Mac users, who need to worry about their Macs being lost or stolen.

macOS High Sierra continues to support full disk encryption, but Mike Bombich, who created Carbon Copy Cloner, has verified a bug in High Sierra that will cause an external drive to have its format changed from HFS+ to APFS when the drive is encrypted in High Sierra.

Enabling encryption on a drive should not alter the underlying drive format. If the drive was HFS+ (Hierarchical File System) before you chose to encrypt it, it should remain an HFS+ drive afterwards. The same is true for APFS (Apple File System) formatted drives; choosing the encryption option shouldn’t change the APFS format of the drive.

Related:A Note On High Sierra Compatibility with Third Party SSDs

Under certain conditions, encrypting a drive will modify the format to APFS without the user being aware of the changes.

The specific conditions are:

• Must be an external drive
• Must not have a Mac operating system installed on the drive

If these two conditions are met, and you select the option to encrypt the drive, by right-clicking the drive icon and selecting Encrypt from the popup menu, the drive will be converted to APFS format and then encrypted.

Even though the drive has been converted to APFS and encrypted, it will continue to work just fine with your Mac running macOS High Sierra. The problem comes about should you ever connect the drive to a Mac running an earlier version of the Mac operating system, or if you boot your Mac to an earlier version of the OS. In either case, the external drive won’t be recognizable by the older operating system.

Our recommendation is not to encrypt your external drive, unless converting to APFS is acceptable to you, and you have no plans to use the drive with earlier versions of the Mac operating system.

Being Logged Out Randomly
If you find yourself occasionally being logged out of your Mac after you upgraded to macOS High Sierra, you can stop worrying; your Mac isn’t possessed. Instead, the upgrade process may have enabled two security options that you may not have been using before.

To correct the phantom logouts, launch System Preferences, either by clicking on its Dock icon, or by selecting System Preferences from the Apple menu.

In the System Preferences window, select the Security & Privacy preference pane.

From the Security & Privacy preference pane, click the Lock icon and enter your administrator credentials. Once the padlock is unlocked, click on the Advanced button.

Either remove the checkmark from “Log out after xx minutes of inactivity” or set the time frame to a longer period to meet your needs. Click the OK button when done.

The second security issue that may be causing the problem is also located in the Security & Privacy preference pane. Select the General tab.

The item: “Require password xx minutes after sleep or screen saver begins” may also be checked. You can remove the checkmark, or modify the amount of time that needs to pass before the screen saver kicks in to better fit your needs. My own preference is to leave this security feature in place, and just adjust the time as needed.

While you’re at it, you may want to jump over to the Desktop & Screen Saver preference pane to adjust the time for when the screen saver starts up.

Select the Screen Saver tab, then use the Start after: dropdown menu to select how much inactive time needs to elapse before the screen saver starts

High Sierra Battery Life is Poor
Another issue that seems to be common is portable Mac battery life being adversely affected after an upgrade to High Sierra. So far, it seems that macOS High Sierra isn’t the culprit; instead, there are a few apps that may need to be updated to make better use of the battery.

Launch Activity Monitor, located at /Applications/ Utilities.

In the Activity Monitor window, select the Energy tab.

In the resulting display, look for apps that are marked as preventing sleep, or are listed as having a high energy impact. Contact the app developer to see if there are updates available for the app to make it perform better with macOS High Sierra.

Unable to Wake From Sleep
I’m not sure what it is about sleep, but the Mac seems to always have issues with sleep after a system upgrade. There have been reports of Macs not being able to wake from sleep after upgrading to High Sierra.

Unrelated, but with the same solution, is a flickering of the display, especially when the Safari browser is open.

You can fix both issues by resetting the NVRAM and then resetting the SMC.

You can find detailed instructions on how to perform these resets in the article:

How to Reset NVRAM, PRAM, SMC on your Mac.

Office 2011 Crashes
If you’re using Office 2011 for the Mac with macOS High Sierra, you’re not having any issues, you’re having occasional crashes, or Office simply refuses to launch at all.

That about covers most of the possibilities. The problem is Microsoft decided not to support Office 11 under macOS High Sierra, meaning they haven’t tested the apps nor are they going to offer any updates to correct any issues. Essentially, Office 2011 is on its own. If it works for you, wonderful, but if you have any issues, it may be time to consider a replacement.

Of course, software apps do get old, and Office 11 has been around for a long time, in software years. If you have a specific need for Microsoft Office, the Office 2016 for Mac version works fine and is fully supported under macOS High Sierra.

If you just need a Word or Excel work-alike that you can use to share files with others, there are a few options available. If you have a suggestion that you know works with High Sierra, please leave a note in the Comments, below.

Mail Stops Notifying You of New Mail

Have you noticed that Mail is no longer alerting you of new incoming messages via the Notifications center? If you’re used to seeing a banner pop up in the top right corner of your Mac’s display with a brief description of a new piece of mail whenever new mail arrives, you may have noticed the banners stopped once you installed High Sierra.

This bug doesn’t seem to affect everyone, but it happens often enough that Apple should be able to fix the issue in a subsequent update of High Sierra.

But you don’t need to wait for Apple; you can fix the issue yourself by opening System Preferences and selecting Notifications.

Mac Mail Sierra App Locking Update

Highlight Mail in the Notifications window sidebar, and then select None as the Mail alert style. Wait a moment, then set the notifications style back to Banners or Alerts, whichever you prefer.

Close the Notifications preference pane.

Launch Mail if it isn’t already running. Mail notifications should now work correctly.

Adobe Photoshop and Illustrator Issues
Adobe Photoshop has a minor issue with High Sierra that prevents the Photoshop window from expanding to full screen whenever the Dock is shown.

Adobe has created a Photoshop plug-in file that can rectify the problem. You’ll find instructions on how to download and install the plug-in at the Adobe Help website.

Adobe Illustrator is experiencing some issues with High Sierra; specifically, the licensing system seems to be broken when the startup drive uses the APFS file system. The result is Illustrator may not launch, or there will be an error message about license problems.

Adobe recommends not upgrading to High Sierra, or not converting to the APFS file system at this time.

There’s an additional issue with Illustrator on macOS High Sierra that results in the wrong color settings being applied; specifically, Emulate Adobe Illustrator 6 becomes the default color setting and is applied to any document you open or new document you create.

The workaround is to manually change the color settings before working with any document.

Select Edit, Color Settings, and then choose the desired settings for the document.

Click OK.

Mac Mail Sierra App Locking Up Mac

Open the document you wish to work on.

You’ll need to repeat these steps each time you launch Illustrator, or before you open a document that uses a different color space.

Other High Sierra Problems and Fixes
macOS High Sierra is still relatively new, and I suspect there will be quite a few additional issues that will crop up. If you encounter any problems with using High Sierra, please feel free to share with our readers by leaving a comment.
