[Newbies] Squeak cannot write to the changes file....

[Milan Vavra]

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
----

Best Regards,

Milan
