Mac OS X Admin Tips¶

Forcing a Mac OS X update¶

Sometimes, Mac OS X just won't update. This just happened to me with Mac OS X Monterrey 12.0.1, where my Mac got stuck for at least three months.

To force an update to, say, Mac OS X Monterrey 12.3, open a terminal and download and launch the full installer:

softwareupdate --fecth-full-installer --full-installer-version 12.3

Copy source directory Source (note the lack of ending / to directory Destination

rsync -ahvz Source Destination

-a : archive mode, by using archive mode we can copy the files recursively and it preserves file permissions, user and group ownership’s.
-v : verbose
-h : human-readable
-z : in this mode it will compress the data

Let's cache the keys store passphrase for a connection done from sour (mac) to dest (linux).

vim ~/.ssh/config

Add the following:

Host dest
    IgnoreUnknown UseKeychain
    UseKeychain yes
    AddKeysToAgent yes
    IdentityFile ~/.ssh/id_your_file
