Missing Fonts in Mac OS X Lion (10.7)

After upgrading to Lion I found it disabled a few of the system fonts. This made lots of websites not display as intended and warnings about Missing Fonts in Pages (which had the benefit of artificially inflating my book’s page count bringing it nearer completion).

Turns out Lion can disable certain fonts in certain circumstances; I did a clean install of Lion on a different drive when running the Install Mac OS X Lion app.

You can re-enable the fonts like this:

  1. Open Font Book, it’s stored in your Applications folder. You’ve got Lion now so you could be fancy and use Launchpad.
  2. Find a font that has been disabled – in my case Verdana was the key one. Right click the font and select Enable ‘font name’ Family:

  3. Repeat this for any other fonts that have been disabled.


You can automatically activate fonts added in the future by ticking Automatic font activation from the Font Book Preferences menu:

Mac OS X Lion’s “Safe files” No Longer Opens Disk Images

Looks like in Safari 5.1 in Lion disk images (.dmg) are no longer classed as “Safe” files after the whole Mac Defender cat and mouse malware saga.

The enabled by default “Open ‘safe’ files after downloading” preference of Safari automatically opens certain types of files as a convenience aid.

I found this quite useful, but I guess it’s just another move closer to an ‘App Store’ only world..

Throttle Bandwidth on MAC OS X

To limit the connection speed on your Mac to a 56k modem for testing your website loading speed, pop this into terminal:

sudo ipfw pipe 1 config bw 56kbit/s
sudo ipfw add pipe 1 dst-port http

You can change 56kbit/s to any speed you want to test with.

To clear it either reboot or use:

sudo ipfw flush
