Did you recently upgrade to the gorgeous new macOS 27 Golden Gate? It comes with fantastic new features and visual upgrades, but over time, even the best operating systems start slowing down. You might notice apps taking longer to launch, or you might see that frustrating 'the disk space is almost full' notification popping up.
The main culprit behind a sluggish Mac is hidden junk data. System logs, application caches, broken temporary files, and leftover remnants from uninstalled apps build up quietly in the background. If you do not clear them out, they eat up your valuable SSD space and drag down your system's performance.

In this step-by-step guide, we will show you exactly how to clean up junk data on macOS 27 Golden Gate. We will look at both the manual way to dig through system folders and a much quicker, safer automatic solution using a dedicated optimization tool.
Why Does macOS 27 Accumulate So Much Junk?
Every time you open a website, launch an app, or edit a photo, your Mac creates temporary files. These are called cache files, and they are designed to help your programs load faster the next time you use them.
However, when apps update or get deleted, these temporary files often stay behind. Over months of regular use, these tiny, harmless files turn into gigabytes of digital clutter. Keeping your Mac fresh requires regular cleanups so your operating system has enough room to breathe and run smoothly.
You can try to manually find and remove the junk data if you are skilled and familiar with the macOS. Otherwise, it's highly suggested to use a professional cleanup tool for Mac, which would be fast and safe to clear junk data.
Method 1: Manually Clean Up Junk Data via Finder
If you have some free time and want to look under the hood of your Mac, you can clean up a large portion of junk data manually. Most of this clutter hides inside hidden user and system libraries.
💡 Note: Be very careful when deleting files manually. If you delete a critical system folder by mistake, your apps might crash, or your Mac might become unstable. Take your time and stick strictly to the paths mentioned below.
1. Clear User Cache Files
Open Finder on your Mac. Look at the top menu bar, click on Go, and then select Go to Folder from the dropdown menu.
Type the following path into the search box exactly as shown and press Enter: ~/Library/Caches
You will see a large collection of folders belonging to different apps. You can select the contents inside these folders and move them to the Trash. Do not delete the main folders themselves—only the files inside them.
2. Remove System and Log Files
Go back to the Go to Folder tool in Finder.
This time, type in: /Library/Logs and hit Enter. This folder holds system logs that you rarely ever need. Move the older log files to the Trash.
You can repeat this process by searching for: ~/Library/Logs to clear out user-specific application logs as well.
3. Empty Your Trash Bin
Many users forget that moving files to the Trash does not actually free up any disk space. The files are still sitting on your drive! Right-click your Trash icon in the dock and select Empty Trash to permanently remove the data.
Method 2: Clean Up Automatically with Donemax
