I'm not sure what happened, but it looks like I was able to get it cleared up in a very round-about way. But somehow Time Machine had the lost disk space in its backup records as space used, so when it tested a new drive for adequate space, it got it wrong. But Time machine was able to restore without including the lost disk space. So both Time Machine and the laptop OS were confused about what the actual utilization was, overstating it by 120 to 135 GB. The utilization on the 500 GB drive is consistent with the OmniDiskSweeper report above. OmniDiskSweeper just counts what is there, but GrandPerspective shows 191GB of 'Miscellaneous used space' (big grey box on the side) and System Profiler lists it as 'Other'. I backed up the 750 GB drive to Time Machine, then successfully restored that backup to the 500 GB drive. I have OS X 10.15.7 running on a 500GB SSD and OmniDiskSweeper, GrandPerspective and System Information show that I have used about 270GB but only have about 30GB free. I then tried restoring to a virgin 500 GB drive and received the message that there was not enough room on the 500 GB drive.
Looking at utilization on the new drive showed that it was consistent with the OmniDiskSweeper report above. I restore from Time Machine to a 750 GB drive using the most current backup.
#GRANDPERSPECTIVE MISCELANEOUS USED SPACE MAC#
Storage under About This Mac shows all disk space, 498.73 GB, allocated to "other". When I look at information for what is in it, some of the big items (Applications, Developer, Library, MSI, System, and Users) add up to about 113 GB of usage, but is that real? If it is, then this might be the problem but I'm guessing I'm looking at linked folders. Information says it's an alias, so I imagine it's a link. But there is a folder with my disk volume name, "MacbookPro3". There is no folder (or volume) there by that name. It looks like there is nothing to do here.ĭf -h output: Filesystem Size Used Avail Capacity Mounted onĭf output: Filesystem 512-blocks Used Available Capacity Mounted on I don't do this often, but I think I would have expected a report of something wrong, which I would then fix by running Repair. I ran Disk Utility Verify and the results reported are Verifying volume “MacbookPro3” Are there any other tools that might tell me where the rest is, or why it is tagged as used? So, by OmniDiskSweeper's account, I have about 140 GB unaccounted for. I htought I used it to scan the whole disk in the past.) (By the way, GrandPerspective version 1.5.1 doesn't seem to be able to scan the whole disk, only folders. I also ran GrandPerspective on the ~Users folder, and it accounted for only 266 GB, which is 21.1 GB short of what OmniDiskSweeper reports. (I got this by running sudo open OmniDiskSweeper.app, which gave the same result as running it without the sudo. OmniDiskSweeper reports a bit more than 358.64 GB once it seems to have settled to final values: Users 287.2 GB If you’re the type who can’t leave well enough alone, then tinker away.I looked at some of the other Q&A here and didn't see a duplicate of this one (e.g., How can I figure out what's slowly eating my HD space? and other linked and related questions).įinder reports that my 500 GB drive is using 499.248 GB. Not satisfied with the system preferences Apple gives you access to on your mac? TinkerTool lets you get at that hidden stuff too numerous to mention.
