Remember when Migration Assistant worked with Disk Images?

Apple Disk Image IconI don’t exactly recall when Apple’s Migration Assistant started logging out the user (10.9ish), but since then it has been a little more irritating to migrate from a dmg or other image format (as opposed to a source hard drive or time machine backup).  Here is a simple Terminal command to mount the image as root and thus keep it mounted after logout.

sudo hdiutil attach diskimage.dmg

This process does require running a checksum, and for larger images that could take a while.  Once you run this command and it completes its verification of the disk image, simply run Migration Assistant and complete the migration.  After migration and a restart, the image is unmounted and you are ready to work on your newly migrated mac. (note: migration can also take quite a while depending on the amount of data)

Happy Birthday GIF!

On this day in 1987 Steve Wilhite while working at CompuServe developed the GIF format.  Thanks to the internet and the fact that internet speeds continue to accelerate they have become the defacto animation format.  Hooray!  It is importent to point out that although the GIF is 30 years old today, the animated version that we are so familiar with did not become available until 1989.  Don’t tell me how to pronounce it. Enjoy my collection.

exFAT vs exFAT!

No exFATThe interoperable file system that is nearly impossible to interoperate.  Introduced in 2006 by Microsoft, it eventually gained compatibility from XP to Windows 10.  Apple introduced support in 10.6.5.  Even Linux got to play thanks to Fuse.  It turns out that any reasonable sized drive prepared in windows will not be compatible with Mac and unable to mount. This is because Apple’s implementation of exFAT requires less then 1048576 bytes per cluster, where as Windows varies it’s cluster size depending on the capacity of the volume.  Best advise for mac people is to format it on windows, but set the block size to 1024. Can we get a new file system now please?

SSL problem, it wasn’t me!

broken keyI just assumed that the problem was related to my recent SSL renewal.  Turns out, Google security recently published Distrusting WoSign and StartCom Certificates and removed them from chrome.  How did I miss this?  It turns out that the SSL on my site has been broken on Chrome for some time.  It must be that I have been using Brave recently as my daily browser.  I moved this site to and it’s working fine for everyone now.  I don’t even know how much time I waisted on this one.  wow.
