Of import Tips

If you have decided to update to High Sierra but have yet to do so, here are a few things (based on the lodge of priority) I highly recommend you check out in advance then you lot can avoid potential issues.

ane. Check your Mac model – Not all Macs, especially old ones, are able to upgrade. Apple has a clear list of which Mac models are supported. You tin can view the specifics here.

2. Make clean upward your Mac – Per Apple tree, High Sierra requires at to the lowest degree 14.3GB of storage infinite to perform the upgrade. The more costless space you have, the meliorate. Plus, it'll take you less fourth dimension to dorsum up. How to clean? There are lots of manual things you can do, but I recommend using CleanMyMac to remove system junk and Gemini 2 to notice large duplicates. That'southward the most effective solution I've constitute. You lot can besides read our detailed guide on the best Mac cleaner software.

3. Backup your data – It's always good practice to backup your Mac in one case in a while — or every bit they say, brand a backup of your backups! Apple also recommends us to do that for major macOS upgrades, just in case. Time Auto is the become-to tool merely y'all can as well use advanced Mac fill-in apps which have some central features Fourth dimension Auto doesn't offering, such as bootable backups, the ability to select which files to backup, lossless compression, etc.

four. Update to 10.12.6 Offset – This helps avoid an issue where your Mac keeps hanging in the "about a minute remaining" window. I establish out the hard mode. If your Mac is currently running an older Sierra version other than 10.12.6, you can't successfully install High Sierra. Yous tin learn more details from Issue 3 beneath.

5. Cull the right time to update – Do NOT install High Sierra at work. You never how long information technology'south going to take. Instead, I call up information technology's best that you set a time to do this on a weekend. The installation process lonely volition take almost ii hours to complete (ideally). Plus, it takes more time to clean and back upwardly your Mac — and bargain with those unexpected issues like the ones I encountered.

All washed? Cracking! Now here is the list of issues and fixes yous may reference in instance of problems show up.

Notation: information technology's very unlikely that you'll see all of the issues beneath, so feel free to navigate through the Table of Contents to jump to the event that is exactly the same or similar to your situation.

During macOS High Sierra Installation

Issue 1: Downloading Process is Slow

Possible cause: Your Internet connection is weak.

How to gear up: Restart your Internet router, or move your Mac machine to a better location with a stronger signal.

For me, information technology only took a few minutes for the download to complete before the installation window popped up. Here are two screenshots I took:

Event 2: Not Enough Disk Space to Install

Possible cause: The startup deejay on the Mac that High Sierra will be installed on lacks storage space. The latest macOS requires at least xiv.3GB of free disk space.

How to set: Gratuitous upwardly storage every bit much as you lot can. Bank check the segmentation for large files, deleting or transferring them elsewhere (especially photos and videos which tend to have much more than space than other types of files).

Besides, unused applications could stack up. It's good practice to uninstall them every bit well. The quickest way is to use CleanMyMac to deep-clean your hard drive and Gemini to observe and remove duplicates or similar files.

For me, I didn't run across this mistake considering my installation "Macintosh Hard disk drive" has 261.21 GB available of 479.89 GB — 54% gratuitous!

Upshot 3: Freezes or Stuck at A Minute Remaining

More details: The installation stops while the progress bar shows information technology'due south nigh finished. It says "Most a minute remaining" (could be "several minutes left" in your example).

Possible cause: Your Mac is running macOS Sierra 10.12.5 or an older version.

How to fix: Take a few minutes to update your Mac to ten.12.six commencement, and so re-install 10.13 High Sierra.

I was really annoyed past this "About a infinitesimal remaining" result — though it said only a minute left, a few hours later the situation was the same. I canceled it, thinking my Internet had been disconnected and re-tried. But I was disappointed to see my Mac hang upwardly once more with the same fault: Stuck at one minute left.

Then, I opened Mac App Store and saw that at that place was an update request (as y'all see from the screenshot below, thankfully I still accept it). I clicked the "UPDATE" button. In about ten minutes, Sierra ten.12.6 was installed. I then proceeded to install Loftier Sierra. The "one infinitesimal remaining" result never reappeared.

Issue 4: Mac Running Hot

Possible crusade: You're multi-tasking while High Sierra has yet to cease installing.

How to fix: Open Activity Monitor and find resources-hogging processes. You tin admission Activeness Monitor past going to Applications > Utilities, or practice a quick Spotlight search. Shut those applications or processes (highlight them and click "X" push) that are over-consuming your CPU and memory. Also, read this Mac overheating article I wrote earlier for other fixes.

While I installed High Sierra, my mid-2012 MacBook Pro did run hot a little bit, but not to a point that information technology needed attention. I institute that once I quit a few normally used apps similar Google Chrome and Post, the fan immediately stopped running loud. I had to switch to my PC for work stuff during those two days, which wasn't a problem for me, fortunately. 🙂

After macOS Loftier Sierra is Installed

Issue 5: Running Slow on Startup

Possible causes:

Your Mac has too many login items (apps or services that automatically open up when your Mac starts up).
The startup deejay on your Mac has limited available storage space.
The Mac is equipped with an HDD (hard disk drive bulldoze) rather than an SSD (solid-state bulldoze). In case you lot wondered near the speed difference, I replaced my MacBook hard drive with a new SSD and the functioning difference was similar night and twenty-four hours. Initially, my Mac took at least thirty seconds to start up, but after the SSD upgrade, it only took ten seconds or so.

How to set: Commencement, click the Apple tree logo on the acme-left and select Organisation Preferences > Users & Groups > Login Items. There you'll see all the items that open up automatically when you lot log in. Highlight those unneeded items and click the "-" icon to disable them.

Then, check whether or non the startup disk is total by going to Nearly This Mac > Storage. Yous'll encounter a colorful bar like this showing you the usage of your hard bulldoze (or flash storage).

Clicking on the "Manage" button gives you a detailed overview of what types of files are taking upwardly the most storage — which is often a direct hint equally to where you lot should get started cleaning up your Mac.

For me, I didn't notice much speed lag after updating to High Sierra, probably because my Mac had an SSD already (its default Hitachi HDD died last year) and it only takes 10 seconds or so to fully kick upwards. Seriously, Macs with SSDs are much faster than those with HDDs.

Issue 6: Mac Cursor Freezes

Possible cause: You enlarged the cursor size.

How to fix: Accommodate the cursor to normal size. Go to Organization Preferences > Accessibility > Display. Under "Cursor size", make sure it points to "Normal".

Consequence vii: App Crashes or Can't Be Opened upon Start

Possible cause: The app is outdated or incompatible with High Sierra.

How to prepare: Bank check the app programmer's official site or Mac App Store to see if there's a newer version. If yes, update to the newer version and re-launch the app.

Note: if the Photos app fails to launch by showing this error "An unexpected error has occurred. Please quit and restart the application", you may need to repair the Photos library. This article has more information on that.

Issue eight: Safari, Chrome, or Firefox Irksome

Possible causes:

The version of your spider web browser is outdated.
Y'all've installed as well many extensions or plugins.
Your computer is infected with Adware and your web browsers are existence redirected to suspicious websites with intrusive flash ads.

How to fix:

First, run an antivirus to check if your machine has been infected with malicious software or Adware.

And then, check if your web browser is up to date. Take Firefox for instance — click on "About Firefox" and Mozilla volition auto-check whether Firefox is up to engagement. Same with Chrome and Safari.

Also, remove unnecessary 3rd-party extensions. For instance, on Safari, go to Preferences > Extensions. Here you'll come across the plugins you've installed. Uninstall or disable those yous don't need. In general, the fewer extensions enabled, the smoother your browsing experience would be.

How to Amend Mac Performance with High Sierra

Declutter your Mac desktop. Many of the states are used to saving everything on the desktop, only that's never a good idea. A cluttered desktop tin seriously slow down a Mac. Additionally, information technology'south bad for productivity. How do y'all solve that? Start by manually creating folders and moving files into them.
Reset NVRAM and SMC. If your Mac is non booting correctly afterwards updating to Loftier Sierra, yous tin can perform a simple NVRAM or SMC resetting. This Apple tree guide, also as this 1, has detailed step-by-step instructions. Make certain you've backed upwards your Mac earlier doing this.
Check Activity Monitor more often. Information technology's normal that when you're running certain tertiary-political party apps, your Mac could slow down or even freeze. Action Monitor is the all-time way to pinpoint those problems. For those apps that accept compatibility issues running with the latest macOS, bank check the developer'southward site to see if there's an update, or plough to alternative apps.
Revert to an older macOS. If your Mac is extremely dull after the High Sierra update, and there doesn't seem to be whatever fixes, revert to a previous macOS version similar Sierra or El Capitan.

Final Words

One last tip: if you tin can, postpone your High Sierra update schedule. Why? Because every major macOS release normally has issues and bugs, High Sierra is no exception.

Example in bespeak: A few days ago a security researcher found a security bug "that makes it like shooting fish in a barrel for hackers to steal passwords and other hidden login credentials from a user'southward arrangement…to requite hackers the ability to access Keychain data in plaintext without knowing the master password." This was reported by Jon Martindale from DigitalTrends. Apple tree responded fast on this by releasing 10.13.i ii days after that.

While macOS High Sierra slowdown bug are less of import than that bug, I imagine Apple will take care of them sooner or later. Hopefully, with a few more than iterations, High Sierra volition be error-free — then you lot can update your Mac with conviction.
