Issue report:

Running brew prune produces the following error:

Error: Permission denied - /usr/local/share/man/man8/prlexec.8

with no additional information given about the issue. Here are the details about the file giving the error (used ls -la | grep prlexec.8 within the directory specified in the error dialog above):

lrwxr-xr-x 1 admin 143B Nov 5 15:52 prlexec.8 -> /Applications/Parallels Desktop.app/Contents/Frameworks/ParallelsVirtualizationSDK.framework/Versions/Current/Resources/English.lproj/prlexec.8

It's associated with Parallels Desktop, and it seems like a symlink.

Here is my OS information, if it helps: macOS Sierra (10.12.3 Beta)

Any help would be appreciated!

P.S. I have tried chown on the prlexec.8 file to test whether changing its ownership to my user account (admin privileges, as shown in the original post after I changed ownership to me) would work but that did not work. I have since changed it back to root:

llrwxr-xr-x 1 root admin 143B Nov 5 15:52 prlexec.8 -> /Applications/Parallels Desktop.app/Contents/Frameworks/ParallelsVirtualizationSDK.framework/Versions/Current/Resources/English.lproj/prlexec.8

but I get the same error.

sudo chown -R $USER /usr/local/share/man but in general this is a bug you need to report to Parallels support.

@MikeMcQuaid worked perfectly, and I'll be reporting it to the Parallels team soon. Thank you! :+)

Got the same error - apparently the Parallels team has not solved this yet.
