For those participating in Apple’s public beta program or developer program, here’s a script that will make a bootable flash drive installer of Sierra for you. Of course, you’ll need to have downloaded and saved the original installer before running it on your mac for this to work.

When an installer is made available to you from Apple, the first thing to do after downloading it is to quit the installer if it auto runs. Insert your blank USB thumb drive, and make sure it’s at least 8GB (16GB recommended).

You can either run the script immediately with the installer app still in your /Applications or /Downloads folder, or you can move the installer first to your preferred location. It doesn’t make any difference to the script since it’ll ask you for the location of both the Installer and the USB drive before doing its thing. It’ll also give you an option to cancel out if you made any mistake in specifying the location or you just change your mind. The script will ask you for an administrator password as it needs elevated privileges to run the createInstallMedia routine.

Note the script continues to run in the background until the installer has been created. It sleeps for an interval of 10 secs between checking the job status. Since it takes around ten minutes for the createInstallMedia routine to finish its work, you could comfortably increase that sleep time 30 secs or more if you desire. The script will present you a dialog when it detects all is done:

To use the bootable installer, just pop it into a mac, reboot holding down the ‘option’ key and choose the USB drive to kick off the installation process on a partition of your choice.

The full script is available here.


Script Debugger 6: the complete review

SD Shot 2

It feels like cheating. When you’ve spent pretty much your entire AppleScripting life behind the wheel of Apple’s austere Script Editor application, taking Script Debugger 6 out for a 20-day spin feels like someone’s let you in on a secret you’re not supposed to know. Hurdles you’ve taught yourself to clear – through considerable effort, frustration and no small amount of bloody-minded tenacity – are removed before you get to them; obstacles you’ve habitually steered around or avoided have disappeared, and dark holes of AppleScript mystery appear, in the light shone on them by SD6, to be not the menacing entities you once feared but new friends that offer ways to do things faster and more effectively. The secret that Script Debugger seems to lay bare is that AppleScripting doesn’t have to be as painful as we’ve been conditioned to believe. And that does feel like a cheat. Read the full review…
