Ways to speed up macOS Golden Gate slow performance and downloads

Just upgraded and discovered macOS Golden Gate is slow? Early Beta testing has made a lot of noise about Golden Gate being faster and more stable than Tahoe, and to be fair, a bit of slowness immediately after the upgrade is actually fairly normal.

There’s a lot going on in the background after an upgrade, and in the first 48 hours, a performance dip is to be expected, but if you’ve also got any unoptimized apps or accumulated clutter on your machine, these can also cause issues.

I’ll look at some common causes and fixes, plus how you can figure out if it's the beta or your setup that's really the issue.

Why does macOS Golden Gate feel slow right after updating?

Golden Gate has been positioned as a sort of speed and refinement update, with Apple boldly promising 30% faster app launches via preloading, a completely rebuilt Spotlight, and even faster AirDrop. (Beta benchmarks from Geekbench confirm real single-core gains vs Tahoe).

The thing is, post-update slowness is not unusual; and if, by the way, you’re on developer or public beta, pre-release software comes with glitches, and that's just to be expected, it’s actually considered normal because so much is happening, including:

• Spotlight is re-indexing, and this results in intensive background CPU use.

• All your iCloud, Photos, and even Mail data are also re-syncing.

• If any of your Apps are not yet supporting Golden Gate, this might cause compatibility problems.

• Tons of login items and launch agents running at startup.

• Low free disk space (you need between 15-20% free for swap and caches).

Also, I should probably also mention here that Golden Gate is Apple-Silicon-only (M1+). So if you're on an Intel-based Mac, you can’t install it, and a slow Mac, in your case, is a different problem entirely.

Quick fixes: macOS Golden Gate is slow​

OK, so this is my quick fix checklist for when macOS Golden Gate is slow.

1. Wait it out

You need to let Spotlight finish its indexing, and let iCloud complete its sync. These are always heaviest in the first 24–48 hours. Just leave your Mac plugged in and awake overnight.

2. Restart

Giving your MacBook a full and proper restart from the main Mac menu will clear away temporary processes and give your OS a chance to rebuild caches cleanly.

3. Check free storage

Go to System Settings > General > Storage. If you’ve got less than 15–20% of free space, then your macOS will struggle with virtual memory. You need to delete large files or offload any data that you can to an external drive or Cloud storage.

4. Reduce browser tabs

It’s easy to forget that open tabs in your browsers consume serious RAM. I’d also think about switching over to Safari if you use Chrome, because it’s not as heavy on resources.

5. Pause heavy cloud sync

I would also think about temporarily pausing iCloud Drive, Dropbox, Google Drive, or OneDrive syncs via their menu bar icons, just until your Mac feels back up to speed.

6. Check Activity Monitor

Open Activity Monitor from Applications > Utilities > CPU tab and then sort by % CPU. I’d immediately quit any process you don’t know, or are not using, or that is sitting at the top of that list.

More fixes if your Mac is still slow

​1. Reduce your login items

In System Settings > General > Login Items & Extensions. Remove anything you don't need launching at startup, like old helper apps, even updaters, and forgotten sync agents.

2. Update all your apps

Check in the  App Store > Updates. For non-App-Store apps, you need to check directly with the developer if they’re pushing any Golden Gate compatibility patches.

3. Give your Mac a tuneup

After any major macOS update, old caches from the previous version can conflict, so giving them a cleanup is going to force your macOS to rebuild new ones. 

If you’re not sure how to do this, I can recommend using CleanMyMac. Actually, this tool can do a lot of things, from helping you manage your background agents with the help of the Performance feature to getting rid of conflicting system caches after a major update by running the Cleanup scan.

I use its Menu App daily to monitor my CPU and RAM usage in real time, too. Test it out for 7 days — get your free trial here.

Is it the OS or your setup? How to tell

When macOS Golden Gate is slow, it’s important to try to figure out if it's your OS or setup.

1. Test in a fresh user account

You can create a new macOS user in System Settings > Users & Groups. Then, log in and use the Mac for at least 30 minutes.

If everything feels alright there, then on your main account, it’s probably your login items, browser extensions, or corrupted preferences causing the slowdown, not Golden Gate itself.

2. Check if slowness fades

If your MacBook speeds up after 48 hours, then indexing was the culprit. Problem solved.

3. Beta-specific advice

If you’re on the developer or public beta, you should really report the issue via Apple's Feedback Assistant; usually, these glitches get ironed out before the main public release.

4. When to consider rolling back

If after a week, things are still slow, and you’re 100% sure all your apps are updated, you’ve tested a fresh user account, and that's no faster, then it’s time to think about reinstalling or rolling back to macOS Tahoe via Time Machine.
