If the caches are cleared it must recreate them again and this takes time. This is an extreme case and the reason it takes so long is because GIMP caches things it needs. (It’s a mechanical disk drive, not an SSD.) I used Dr Cleaner to optimise the memory and clear the junk, then started GIMP again. For example, I started GIMP, a free photo editor, and it took 10 seconds to start up. By clearing the caches you will slow down the computer.
Click the menu button and it explains what these junk file are - mainly caches.Ĭaches speed up the Mac by storing frequently used data where it can easily be accessed. The Disk section of Dr Cleaner shows the amount of space that can be reclaimed by removing junk files. Some may, depending on how they use their Mac, but I don't use one and haven't seen any benefit when I have.

Has Apple been doing it wrong all these years? Do Apple's OS X programmers not know how to do memory management? I am not conviced most people benefit from a memory manager. The free memory makes loading new apps faster, but when data is needed in the compressed memory it is slightly slower to access. Cleaner, more memory is free, but also more is compressed. Does this make the Mac better? In some ways it does, but in other ways it doesn’t. Cleaner also performs some cleaning automatically, such as when you quit an application. There is an Optimize button to force OS X to clean up the memory and Dr.

Provided there is some free memory, the Mac will run at full speed. Memory usage is a complicated subject and even when it is all used and none is free, OS X still lets you start new apps and carry on working. It is worth keeping an eye on the amount used and if it gets close to 100%, it means your Mac could benefit from a RAM upgrade. Cleaner is clearly the sum of the four types. This reveals a drop-down panel that shows the memory usage and disk space that can be cleaned.Ĭlick the menu button (three dots) and there is a description of the memory usage showing the app memory, file cache, wired, compressed and used. It displays the memory used as a percentage, which is useful, but more information is displayed when it is clicked. Perhaps saying your Mac will run like new is a slight exaggeration, but it aims to help OS X and your apps run better and by cleaning junk files off the disk drive results the idea is that there is less clutter and more disk space.ĭr Cleaner is a menu bar extra that can be set to automatically run on startup. Cleaner is from security company Trend Micro and it cleans and optimises. There are many disk cleanup tools and memory optimisation utilities, but there may be room for one more and this one is an interesting app.
