P: Save For Web - "A write permissions error has occurred" - on macOS (Dropbox issue)

Photoshop Beta 27.0.0.  Updated this morning 19-09-2025 and this ugly bug roared his head.

No solutions offered here work for me. This is clearly an Adobe created problem with Mac OS system security. 

I had no trouble before this update, but now, hitting 'save for web' gets me the dredded 'A write permissions error has occurred.' message. Dropbox is turned off, makes no backups anyway (never), PS beta has been added to the security panel with full disk access, and the app itself had all permissions 'system,wheel, eveyone' set to read & write.

By now (years of reports), Adobe should know where this bug is located and why this happens, so their programmers can avoid it from occuring. No?

OMG - Thank you soooo much!! 
I've tried everything mentioned previosly and nothing worked. At least now I can save the vi the browser animated gif.

You can download Rosetta from Apple.

"I am also unable to save for web/legacy... I'm running an up-to-date version of PS on Ventura 13.4.1"

Are you using an Apple Silicon chip computer?  Do you have Rosetta 2 to support legacy features and plugins?

I am also unable to save for web/legacy and need to export an animated gif. As a temporary solution I exported to Render Video. I'm running an up-to-date version of PS on Ventura 13.4.1. Oh, and I do not have anything related to Dropbox on my system, so that it not the culprit.

@OKBoomer61 in this case, it is Apple that you need to "thank". They are the ones that mandated the change, in order to prevent malicious apps from interacting with your machine without your consent.

That said, I do not remember if Apple's own apps need to be added there, if it is the case, trusted Developers like Adobe should be grandfathered...

Why is this still happening.

Full disk access to ps did not help, not saving to dropbox, stopping sync/backups, nothing helps. If the export as could export animated gifs we wouldnt need this legacy thing that no longer works. It's such a key feature - how am i supposed to make the gifs now.. It's been over a year. 

This worked for me. Actually, I was surprised to see that Photoshop didn't have full access already. Once I assigned full access to Photoshop then I was able to save for web again. I do hundreds of jpeg save for webs each week and this was crippling my work flow. Adobe, please don't mess with things that have worked for decades. I've been an Adobe customer for 30 years and it's getting to where I don't want to ever do upgrades because there is usually some big problem that affects my work performance.
