Why Does MacBook Pro Internal Hard Drive Keep Filling Up Automatically

My MacBook Pro has a 256GB HD. I found the internal hard drive automatically filling up on its own. I cleared over 1.3 GB of space on my Mac, but the free space is not increased, even though I haven’t saved anything to my Mac, only briefly used some apps. My MBP also runs out of system memory (8GB of RAM) from even simple tasks. My MacBook Pro now runs slowly and heats up, how can I accelerate it?

Which kind of apps did you use? Some apps like Photoshop and Microsoft Office may automatically save some files onto your Mac. As for the memory, your Mac always continuously generates system cache, user cache, user log, etc., since it turns on and runs, especially when you run multiple apps at a time. These cache files will consume your memory quickly and make your Mac run slowly.

I think you need a Mac cleaner to keep your Mac in its best performance. I’ve used iBoysoft DiskGeeker, an all-in-one disk management tool. It supports scanning types of junk files on your Mac for one-click deletion, such as system cache, user cache, user log files, trash, outdated downloads, etc.

With it, Mac cleaning becomes much easier and quicker. You can always enjoy the fast speed of your Mac.

  1. Download iBoysoft DiskGeeker for Mac, install and open it.
  2. Select the user data volume (Macintosh HD - Data or macOS - Data) and click Clean Junk.
  3. Select the scanned junk files and click Clean to remove them from your Mac.

After that, the storage space of your Mac internal hard drive will be released immediately.

If your MacBook Pro’s internal hard drive is filling up automatically, you probably turned on Time Machine auto-backup. When your Time Machine backup drive isn’t connected, macOS creates local snapshots on your internal drive and eats the space. You are advised to clean up your Mac regularly to accelerate it.
