I occasionally run into weird permission problems after a restore of files and folders on my machine, I think it has to do with OSX trying to protect me from myself.

Today I needed to fire up my coding environment on my Mac Mini, so I jumped into the folder for the code that I wanted to update using SourceTree, and did (what I thought was going to be) a quick pull, only to get a weird error message.

I figured it was probably something goofy, so I went to the command line, only to get another weird error:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

1	xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

Well, I’ve seen that before, and knew that message was probably because I’ve updated the OS a few times since I last coded. Basically it means the XCode command line tools are missing. Fixing that is easy: just run:

xcode-select --install

1	xcode-select --install

This fires up the Xcode installer, which will ask you if you want to install Xcode, or just the command line tools. In this case I don’t need Xcode, so I chose the latter.

That took a pretty long time (it was on “about a minute left” for at least 10 minutes), which was a bit worrisome, but not all that unusual.

Going back to the command line, I tried to do my “git pull” only to get another error:

fatal: Unable to write new index file

1	fatal: Unable to write new index file

OK, weird – why can’t it write that. Found a few things online that suggested running “git gc” might fix it, so I tried that, but that just gave me this error:

fatal: failed to write ref-pack file
error: failed to run pack-refs

1 2	fatal: failed to write ref-pack file error: failed to run pack-refs

More curious Googling, and finding the suggestion to look at the extended file permissions, so I tried that:

Wait, what’s this “group:everyone deny delete” ? Well, no wonder I can’t run stuff that updates these folders. More Googling and I find the right switch for chmod to clear out the extended permissions:

sudo chmod -R -N .git

1	sudo chmod -R -N .git

Note that I had the two flags reversed the first time and the command told me it couldn’t find a file named “-R”. After running the above, the folder permissions looked more normal:

And my commands worked as expected.

I get a chuckle over this every time it happens. Something in one of the many synch tools I use does some sort of conversion of birth dates, and I end up with alerts on my Mac that tell me somebody is having a really great birthday:

I also see the opposite where I’ll get a reminder that today is somebody’s second or third birthday.

In the case of the ones where they show up younger, it’s usually because wherever I got their birthdate from originally, they didn’t put in the year. So that usually ends up being the year that the contact was entered into my address book.

But in the case of the incredibly old dates, my address book typically has an 1800’s date, so my guess is it’s some system breaking on a date overrun. I’ve also noticed that sometimes these contacts have two birth dates in my address book (again, some symptom of a synch problem), so for instance Reinald has both a birthday in the 1800’s and one a littler more reasonable than that.
