I have a lot of old apps (for reference only) on my MacPro OSX El Cap 10.11.6.I need to free up disk space. Can I safely do this?

May I safely remove these Old Apps (for reference only) from my start up drive? Will I be able to continue to open old files, such a those in PhotoShop that were created prior to CS6?

Mac Pro, OS X 10.11

Removing apps will hardly create a lot of free space.

Try and describe your problem in detail.

Files that take up the most space are usually movies, images and music.

Copy them over to an external drive, then delete them from your internal.


If you really have a Mac Pro, there are four internal drive bays, so how are you running

out of disk space.


Or do you really mean you have a MacBook Pro.

I do have a Mac Pro, early 2008, running the max OS allowed--OSX El Cap 10.11.6, w/a 1 TB SSD. The 4 internal drive bays are filled with the max internal size. Memory is 24 GB 800 MHz DD2 FB-Dimm. I am not a techie, so can't decipher this other than this is the greatest amt memory possible on my MacPro. The Start Up disk is almost full and the computer is unhappy. I am sure that the problem lies in that I have 1000s of fotos + other info on these internal drives, which are backed up each night on an external drive. I'd prefer not to delete the info on the internal drives, as having only one for these files is a bit nerve-racking. So, it appears that on the start-up drive in applications there are a bunch of old version of Adobe apps that I don't think that I am using, assuming that I can open old files created with the old apps if I only want to use CS6. These old apps are in a file called Old Apps (for reference only). They do take up a bit of space. I'd like to get rid of these, if possible.

Ok so you are unwilling to free up space on your Startup SSD, if you want to uninstall your Adobe apps,

then look in their respective folders for the uninstaller app.

The general rule of thumb is to keep at least 15-20GBs of your hard drive free, the OS needs to do its housekeeping

as it is writing and moving files all the time. Have you enabled TRIM on your SSD.

What does your phrase, 'the computer is unhappy' mean. Have you checked the drives health.

Download this app, https://binaryfruit.com/drivedx there is a free trail period.


The 2008 MacPro is a great machine, I am writing to you on one, still going strong

after 12 years, no unhappy computer here.

To Eau Rouge: I have not enabled TRIM. I did check out the geek site, but am unable to determine if my PNY SSD is on the black list. The BinaryFruit app looks promising, tho have not yet installed it. S.M.A.R.T status is verified, though.

SSD history: SSD was installed by an independent computer shop. The manager there was on steriods and rearranged and changed files on the computer. I've never thoroughly understood what was done, but am discovering a few things, like the "old apps for reference only" folder was in the downloads file. Another copy of the current apps is located in one of my internal storage drives in a Mavericks 1TB folder which appears to be identical to that on the El Cap SSD--that seems unnecessarily redundant. In other words, my computer is a mess and this may be accounting for the lack of necessary disk space. At this point, there is only 1.61 GB space on the El Cap SSD, no where near what you indicated is necessary for housekeeping. Advice, please.

You own a 2008 MacPro and let another person install an SSD. The whole point of the MacPro silver towers was that

they were USER upgradeable, no outside interference necessary. See where it got you.

Running with only 1.61GBs of free space is dangerous and could cause your mac to lock up and be completely unusable.

You need to free up space on that disk immediately. Once you have done that then you can investigate what is duplicated on your drives and delete items you no longer need.


To be on the safe side you really need to work out what you want your mac to do for you.

Use a bit of paper and write down what apps you want and need to open the files you have.

Any apps you don't need, delete them, or if they are apps like Photoshop etc that distribute

their files throughout your mac you will need to use their uninstallers.


Take the weekend to sort it out, the mac is your responsibility and not some other in an independent computer shop,

involving a third party always ends in a mess.

In past years, in addition to changing out the nVIDIA card twice, I've also filled the 4 internal slots with internal drives. Currently, to allow for adequaate housekeeping space, I've moved much of my photo-related work and references onto an external 5TB drive. The recommended 15-20 GBs of space--and more--now exists.


As we both are working on 2008 MacPros, I would be interested in knowing your OSX and your internal configuration. Obviously, you are savvy enough to have configured your machine in the most advantageous way.


Thank you.
