How to get CleanMyMac 4.4.7

I had a little problem about updating macOS Catalina yesterday and waited until the computer finally returned to normal at night. In order to effectively clean up the system trash, I am going to use CleanMyMac to clean up the system.

CleanMyMac X is a powerful Mac system garbage cleaning tool, which can remove extra language packs, system caches, applications, PowerPc software runtime libraries, etc. on the Mac system. It is a good tool for thinning your hard drive. It should be considered the best system cleaning software on macOS.

The resolution of macOS beta update prompts insufficient space, infinite loop restart

Before going out this morning, I downloaded the new macOS Catalina beta system and let it update itself. When I came back in the afternoon, I found that the system update failed, indicating that the storage space was insufficient. I encountered this situation in the past, I restarted the computer and entered the old system, and then re-updated after setting some space free.

However this time things are different. On the one hand, I still have 20GB of free hard disk space before the update. According to common sense, I should not be prompted for insufficient space. On the other hand, I could not enter the old system after the update fails. I updated the system in an infinite loop, and the update fails.
