On 2017 iMac 500GB SSD with OS13.7.4 (22H420). Mail crashing from full drive that isn't possible.

My Mail keeps crashing. Reports drive is full. When I delete mail files they show up again within seconds. My drive shows normal amount of space taken by usual items and the rest is filled with Data that it tells me totals 6.43TB and no matter what I do that number does not decrease at all. Analysis shows it's all in Mail but I have no clue how that can be. TeckTool, MalWareBytes, and Disk Utility show no problems.

CleanMyMac claims another victim. It's one of several apps that most of the experienced contributors to these forums consider akin to malware.


First, there is no reason to ever install or run any 3rd party "cleaning", "optimizing", "speed-up", anti-virus, VPN or security apps on your Mac.  This documents describe what you need to know and do in order to protect your Mac: Effective defenses against malware and other threats - Apple Community and Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support.  


There are no known viruses, i.e. self propagating, for Macs.  There are, however, adware and malware which require the user to install although unwittingly most of the time thru sneaky links, etc.   


Anti Virus developers try to group all types as viruses into their ad campaigns of fear.  They do a poor job of the detecting and isolating the adware and malware.  Since there are no viruses these apps use up a lot of system resources searching for what is non-existent and adversely affect system and app performance.


There is one app, Malwarebytes, which was developed by a long time contributor to these forums and a highly respected member of the computer security community, that is designed solely to seek out adware and known malware and remove it.  The free version is more than adequate for most users.  


Unless you're using a true VPN tunnel, such as between you and your employer's, school's or bank's servers, they provide false security from a privacy standpoint. 


Uninstall CMM according to the developer's instructions. Then you can check to see if you've removed all of the supporting files by downloading and running the shareware app Find Any File to search for any files with the application's or the developer's name in the file name.  For CMM you'd do the following search(es): 


1 - Name contains cleanmymac

2 - Names contains macaw


Any files that are found can be dragged from the search results window to the Desktop or Trash bin in the Dock for deletion.


FAF can search areas that Spotlight can't like invisible folders, system folders and packages.  


If you get warnings that the file can't be deleted because it is in use or used by another app boot into Safe Mode according to How to use safe mode on your Mac and delete from there.


Note:  if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode.  This makes it act as a wired keyboard as will assure a successful boot into Safe Mode.


After you've rid your Mac of all traces of CMM boot into the Recovery volume (boot with the Command + R keys held down, select Disk Utility and run Disk First Aid on all available volumes. Then reboot normally.

The Mail app seems to be a problem. It's way up there at the top in CPU (99.56%), RAM (12.69 GB) and Energy (34 out of 100) use.


Mail has also crashed 19 times and high CPU use 8 times since 2/22/2025.


You might Boot into the Recovery volume (boot with the Command + R keys held down  - Intel Macs) or  (How to Boot an M1 Mac into Recovery Mode), select Disk Utility and run Disk First Aid on as many volumes as you can find.

If you don't save your email to your computer you may be reaching the limit of the free 5 GB of iCloud space that you get with the iCloud account. Go to System/iCloud/Apple ID settings pane and see how much free space you have on your iCloud. I save all of my email to my Mac and the only emails that are saved to iCloud are from my iPhone. Messages are the biggest user of iCloud space.

Thank you so much for this quick response to my dilemma. I will followup on your suggestions sometime in the next week as am attending other duties for a few days. Will let you know how things go and if necessary follow your further instructions to pursue further action if necessary. Once things clear up I will be purchasing a 24" iMac but don't want to until I'm sure I won't pass something on to that one.

Regards, Larry Wellenstein

Larry,

By the way, the M4 based Mac mini is a MUCH MUCH better value and IMHO machine than the current iMac line. All it needs is a display and you are done. For about $1400 you can get a 16GB RAM, 1TB SSD and a nice 32" display, vs. about $1700 for an iMac with a 24" display.


I purchased a Mac Mini M4 with 1 TB SSD and 16 GB of RAM with a 32" LG 4K monitor w/speakers for $1417, $648 less than a similarly configured 24" iMac. A terrific combination.

While I appreciate your contribution, I don't think you actually read what my issues were nor looked at the Etre report nor looked at the storage. I have generated a new report using tips from your previous post concerning my use of CMM some 7 years ago. While it got rid of the vestiges of CMM that remained, it seems I now have even more Mail data listed. And yes, please explain how I could have something like 6 TB of mail data residing on a 500GB drive. Neither the Genius Bar people nor Apple support couId understand how that could be. I recognize that I'm probably at fault in some way for causing these issues but am really interested in getting rid of the problems so I don't pass them on to a new Mac. Thank you very much, and thank you forever more if you can solve my problems here.

Description: 

Greetings, I have 2 problems; I think related. The Genius Bar at my A

pple Store spent 2 hours with the machine and were totally stumped. T

hey contacted Apple Support and explained the issues to them and asked

that an appropriate person call me at home later in the day. We then 

spent an hour and a half with her sharing my screen. She had absolutel

y no answer for how it was possible to have a storage issue presented 

as mine. After all this time it seemed as if the me.com account issue 

was resolved by her, but the next day it presented exactly as before. 

I would be grateful if after looking at the Etre report I will be at

taching, that someone could come up with a solution for these two prob

lems. I do not merely wish to be told what I’ve done wrong, but given

advice on what I have to do to correct the problems. I am going to p

urchase a new Mac ASAP and do not wish to pass on any of this to it.

1. Soon after I updated the OS I believe in December or early January,

I began getting a message to “enter your password for lmwellenstein@m

e.com in order to continue using Apple Media Services”. Sometime after

purchasing this computer, I had called Apple (at least 6 years ago) t

o delete that account and was assured this was done. I had no reason t

o think it had not been until these messages began a few weeks ago. 

If I delete the message, it is repeated. If I delete again, it goes a

way I can go on with what I’m doing with seemingly no problem. This i

ssue eventually returns (at no specific time that I can discern) and i

f then I select continue, I’m asked to enter the password. By entering

the password I previously had for the account, I’m told that the acco

unt doesn’t exist. I then cancel the request twice as before. 

Someone suggests that because I once had Clean My Mac on this machine

it is the cause of the problem. While I was made aware 7 years ago CM

M had a bad rep and removed it, I thought according to specs, but perh

aps not. Never-the-less, I find it hard to believe that it is the sud

den cause of this combination of issues which never before occured. 

2. About 2 weeks after the above issue started, I began getting notice

s that the changes I had made in mail could not be saved because my ho

me disc was full. 

I checked the storage on “about my iMac”. It initially shows I have 

116 GB available out of 500 GB. After a few seconds it then changes to

: 5.62 TERRABYTES of my 500 GB drive used and 5.56 TB (yes, you read t

hat right) of that 5.62 TB is data taken up as data in Mail. This is i

ncredible to me and even after removing everything I can and then movi

ng all files and photos to external drives, it remains showing me 5.56

GB. And no, I do not store any mail on the cloud. 

It seems that I can still use email but it will often crash while I a

m trying to delete something or trash something. A report is supposedl

y sent to Apple and then mail is re-opened. Probably connected to thi

s issue is the fact that when I delete messages, whether 10 or 200, th

ey all are put back within seconds. I am also collecting an ever incr

easing number of folders labeled “import” (19 of these at the moment) 

or “recovered messages”. I have not personally created any of these f

olders.

A sincere thanks to each and everyone in advance for your kind and exp

ert consideration of my dilemma.
