Thanks to those who offered assistance. I now suspect that something is wrong with my system, leading to the failure. When I switch to a different user account and try again I don't have the problem. So, I guess I need to rebuild my system before trying to use the 5.1 version of Squeak.

Thanks very much for your help.

Having researched this a bit further...

== This issue is caused by the ---- com.apple.quarantine ---- macOS extended attribute.

*Either move the extracted folder before you double click it or remove the extended attribute*.

* When the ---- Squeak5.1-16549-32bit-201701281910-macOS.zip ---- zip file is downloaded, macOS Sierra 10.12.5 puts a ---- com.apple.quarantine ---- extended attribute on it.

== When you double click that file in Finder (or use unzip in Terminal) macOS Sierra 10.12.5 also puts a ---- com.apple.quarantine ---- extended attribute on the ---- Squeak5.1-16549-32bit.app ---- folder that gets extracted from the zip file.

== Moving a folder in Finder (or using mv in Termminal) modifies the ---- com.apple.quarantine ---- extended attribute of the folder being moved.

After the move, ---- Squeak5.1-16549-32bit.app ---- no longer causes the issue.

You can display and modify extended attributes in Terminal.

== To see extended attributes of all files in the current directory. * In Terminal, do ---- ls -l@ ----

== To see the extended attributes of a file/directory * In Terminal, do ---- xattr -l Squeak5.1-16549-32bit.app ----

== To remove all extended attributes of a file/directory * In Terminal, do ---- xattr -c Squeak5.1-16549-32bit.app ----

== To remove the com.apple.quarantine extended attribute of a file/directory * In Terminal, do ---- xattr -d com.apple.quarantine Squeak5.1-16549-32bit.app ----

I notice that my older version of Squeak 5.0 works. But not the new version. Even if I follow your instructions.

I've just installed Squeak and started playing with it but it complains that it doesn't have write access to a needed folder

/private/var/folders/rz/...

I've tried giving full access to all the folders from /private/var/folders/ down but it doesn't solve the problem.

This looks like a known problem on newer OS X (macOS) versions.

I presume you have downloaded the app and unpacked it in the Downloads folder and have run it from there. macOS tries to be helpful and moves it away and denies any file read/write.

So what can you do? Once you have downloaded and unzipped the App, >> Move it away from the Downloads folder <<. Where does not matter too much. /Applications or the Desktop are common choices and should work. Note that this only works if you move the App before you open it once. So best is to delete the "old" app, Unzip, move the new app and then start it.
