recommended disk cleaner for macbook pro 2015

There are NO third party applications that will do that on a Mac. Mac OSX is designed to do all of that work internally. The only additional component needed is you (by not installing junk software).

If you are having issues with your MBP, describe the symptoms, then perhaps we can find the remedies.

Ciao.

You can find applications that will claim to clean up your Mac, but in general they are not needed. If your Mac has slowed down over time it may be a lack of storage space for temporary files, a lack of RAM, or other bottleneck that should be diagnosed.

"Useless" is relative as files that are not useful to one user are very useful to another, so Apple and developers install them all. Removing them is not always helpful because they are often reinstalled at the next application or system update.

Describe the problems you are having and with which specific applications, because often these are application-specific problems.

Try downloading EtreCheck https://etrecheck.com/ and post the results here.

Hopefully this will allow someone to identify what is slowing your computer down.

Try downloading and installing OmniDiskSweeper: OmniDiskSweeper

OmniDiskSweeper will sort your files by size and show you where they are located. See the following video on OmniDiskSweeper. Using OmniDiskSweeper

This may give you an idea of what is happening.

My storage states I've used over 20gb, of which 17gb is listed in "Other", this isn't possible, being that its just as it was when bought, other then adding a printer and adobe.

The question is, Adobe what? Adobe has a long list of products. And it certainly is possible depending on which Adobe product you are using. For example, if you edit video, chances are the program will normally consume increasing amounts of disk space for its Media Cache and other temporary files. I called it "normal" because this is as designed in that the Media Cache is for enhancing performance, unless the disk is too small. The standard practice for pro workstations is to designate a separate large and fast disk for things like the Media Cache. This is not an Adobe failing because it is also true of pro Apple media editors like Final Cut Pro or Logic Pro.

Say which specific Adobe software you are using so we can give more specific recommendations. For example I know where the cache empty commands are for Adobe Bridge, After Effects, and one or two others.

OK, Flash Player shouldn't use up disk space. Are you using apps like iMovie, GarageBand, iDVD? Do you run a virtual machine like Parallels Desktop, VMware Fusion, or Virtualbox?

Run etrecheck. That will tell more than you can ... it knows what to look for.

For information about the Other category in the Storage display, please see this support article. If the display seems to be inaccurate, try rebuilding the Spotlight index.

Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:

iPhoto ▹ Empty Trash

In Photos:

File ▹ Show Recently Deleted ▹ Delete All

Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.

According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.

When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.

See this support article for some simple ways to free up storage space. A common waste of space is old iTunes backups of mobile devices. As illustrated in this support article, select the Devices tab in the iTunes preferences window, select the backups you want to delete, and click Delete Backups. Keep at least one backup of each device that you still use.

You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later.

Deleting files inside a photo or iTunes library will corrupt the library. Changes to such a library must be made from within the application that created it. The same goes for Mail files.

Proceed further only if the problem isn't solved by the above steps.

ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.

Back up all data now.

Install the app in the Applications folder as usual. Quit it if it's running.

Triple-click anywhere in the line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C.

security execute-with-privileges /A*/OmniDiskSweeper.app/*/M*/* 2>&-

Launch the built-in Terminal application in any one of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

Paste into the Terminal window by pressing command-V. You'll be prompted for your login password.

The application window will open behind other open windows. When you scan a volume, the window will eventually show all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.

I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.

When you're done with the app, quit it and also quit Terminal.

Try uninstalling Steam and ejecting the USB flash drive and then reboot and see if that helps.

Open Finder and from Top Menu select “Go” and press and hold “Option” key. You will see the folder “Library” appear.

Click on Library.

Open “Application Support” folder.

Drag the Steam folder to the Trash.

Empty trash. You may need to reboot.
