Trash Can emptying OK, but with no corresponding increase in the space on my iMac SSD

Thank you for your helpful & prompt response.

The problem with the storage space has been occurring for in excess of several days now, so I don't believe that it's actually happening just because of SSDs having a different garbage collection routine.

Nevertheless I'll wait for a few days to see if it gets any better.

Many thanks.

Thank you again Barney.

Only around 40% of the SSD space has been used & when replacing the original iMac Fusion drive with an SSD approx. 3 years ago, I think on reflection I could easily have managed with a 250 or 500Gb SSD instead of 1Tb. I just wasn't sure so I chose the latter option.

Anyway in the last couple of days your suggestion that SSDs are sometimes reluctant to release working space, seems to be very true indeed, the Finder status bar now shows 559.12Gb available. I was getting readings (sometimes not changing that regularly) in the past couple of weeks in the 530 to 540Gb range.

Maybe, the idea that something else has caused a problem is connected with Lightroom & Photoshop processing of relatively large images & deleting those, including substantial adjustments, which just haven't worked.

Kind regards,

Richard Firth
