I have my web development environment on a mac pro running on OS X version 10.6. I'm considering upgrading it to Mac OS X 10.7.

Will it upgrade smoothly or do I have to reinstall mysql, perl and so on? I am especially scared for upgrading MySQL and the databases.

To answer remarks here below, I don't remember how I installed MySQL in the first place, but for what I remember, it didn't came out of the box. That's why I am scared it might get removed.

Concerning the os version, I tend to say as close possible to the version that came with the mac at the time. The more recent the OS the more resource hungry they are. I prefer to have a fast mac then an up to date OS. I would stay to 10.6, but there are some applications could help me and are only running on 10.7.

  • Is your current MySQL compatible with Mountain Lion?

  • How did you install MySQL - also what is your reason for upgrading and why not directly to 10.9? or just leave at 10,6

  • Usually my MySQL installation works after upgrading. You may want to review your php.ini to correct the position of the MySQL socket (php.ini gets changed by the upgrades). dev.mysql.com/doc/refman/5.1/en/macosx-installation-notes.html

MySQL, as well as the databases, is still there and working after upgrading. This said, all the settings, php, mysql, apache, virtual hosts, where resetted to the default. Very annoying I have to rebuild all my development environment.
