How to uninstall JASP on Mac
Save your analyses and retain the original datasets before removing JASP. Its official FAQ lists supported data formats; those input files are separate from application settings. Copy needed analysis files and confirm they open before uninstalling.
Quit and remove the app
Save your work and quit JASP with Cmd + Q. Move the Mac app from Applications to the Trash after checking the backup. Keep separately saved projects and source data in place.
Review local data
~/Library/Application Support/JASPheld application data in the test; on that disk the lowercasejaspspelling was the same folder. Inspect and copy wanted contents.~/Library/Caches/JASPis separate cache storage.~/Library/Preferences/org.jasp-stats.JASP.plistis a historical settings location in the cask. Zap also names~/.JASP; the test did not establish that it held your project files.
After checking the analysis and settings backups and quitting, press Shift + Command + G in Finder to open ~/Library/Application Support/JASP, ~/Library/Caches/JASP and ~/Library/Preferences/org.jasp-stats.JASP.plist when present. Inspect ~/.JASP separately if it exists, then move only verified JASP items you chose to discard to the Trash. Keep independently saved datasets and analyses.
Check the result
pgrep -ifl JASP
ls -ld /Applications/JASP.app "$HOME/Library/Application Support/JASP" "$HOME/Library/Caches/JASP" "$HOME/.JASP"
No process output means this name was not found, not that every helper has gone. Check any match against the app’s actual executable path. A missing-path error from ls means only that location is absent; permission errors leave its state unknown. A surviving folder can be intentional data to keep.
If you installed it with Homebrew
The cask’s Intel branch is disabled for its Gatekeeper check. Zap includes ~/.JASP, Application Support, cache, historical preferences and saved state. A manual zap can reset application data; save projects first.
To uninstall without zap, use:
brew uninstall --cask jasp
Mole checks Homebrew's full removal list and skips --zap when it reaches unchecked data, shared files or anything it cannot verify. It still removes the leftovers you selected. A direct brew uninstall --cask --zap jasp runs Homebrew’s full zap list without consulting Mole’s checkboxes.
What Mole lists
Mole selects the app and attributable cache/preference rows by default. ~/Library/Application Support/JASP is listed unchecked when Remove data and settings with apps in General > Cleaning is off. Turning it on can preselect eligible app data; uncheck wanted settings to keep them. Saved datasets and analyses in independently chosen folders are not a blanket uninstall target.
What this test covered
The official arm64 JASP app was tested on September 21 and reinstalled and removed with a development build on September 26, 2026. The later select-all run removed all five listed items. Actual research projects, data recovery and a Homebrew installation were not verified.
