It’s a Mac app that fills the gap between Siri and your Spotlight search by allowing you to automate tasks and perform advanced functions that, frankly, Siri should be able to handle on its own. Once I have exported this Hazel rule on one Mac and imported it on the other Mac(s), any changes I make to the hazel-newvolume.sh script will be reflected on all of the computers which sync via Dropbox.The best business laptops from Apple, Lenovo, Dell, and moreġ0 best laptops of 2023: tested and reviewed You can then import the Volumes.hazelrules file by either: a) using the same 'gear' menu in the above image (choose "Import Rules…"), or b) drag the Volumes.hazelrules file to the /Volumes/ item under "Folders" or c) simply double-click the Volumes.hazelrules file and choose to import it into Volumes: On the other Macs, make sure you have an entry for /Volumes/ under Folders.(see image) I'd suggest putting the Volumes.hazelrules file in Dropbox to make it easier to import on your other Macs. )Ĭlick the gear icon in Hazel and Export "Volumes" rules from Hazel. ( Note: on one computer which does not have enough internal storage for my Dropbox, I told the Dropbox.app to put its folder on /Volumes/External/Dropbox but then I linked it to /Users/luomat/Dropbox/. You can put it wherever you want in your Dropbox, as long as the paths are the same on all of your Macs. The full path to hazel-newvolume.sh is /Users/luomat/Dropbox/bin/hazel-newvolume.sh on all of my Macs which sync via Dropbox. Instead of using an embedded script, use an external script file which is saved on Dropbox. Hazel doesn't sync its rules across Macs, but you can sort of fake it when you are creating a rule which points to a shell script on Dropbox.Ĭreate the rule on one Mac, including the "Run Shell Script" part. The two Display Notifications are mostly for debugging purposes, so I can tell when the recipe has started and finished. "Dated Added" "is after" "Date Last Matched" means that it will run once for every new item added to /Volumes/ (so the script will need to be smart enough to tell when it is not being used on a dmg). Choose /Volumes/ as the Folder and then create a new rule using the "+" under “Rules”: To start with I decided to only deal with the most common scenario: a DMG is mounted and it has an app which is not an installer. if no, does that mean we should stop the installation or just inform the user, who might want to replace a newer, buggier version of an app with an older version? (Our answer may depend somewhat on what we do with apps that are already installed.).Is the version we are considering installing newer than the currently installed version? If the app or any of its helper apps are running, can they be quit safely (or at least, relatively safely)? Once we have determined what needs to be installed, there are more considerations to make:ĭoes it have any 'helper' apps that are running? There may be more than one app and more than one pkg dmg (for example: MailMate's DMG also includes SpamSieve) It is a prefPane which needs to be installed either to ~/Library/PreferencePanes/ or /Library/PreferencePanes/ app but it is an installer (iTunes, Default Folder X, etc) pkg file which needs to be installed (second most common) app which needs to be copied to /Applications/. How can you tell if a new volume is a DMG?Īssuming it is determined to be a DMG, how do you identify what needs to be installed? There are several possibilities, the first two is the most likely, but the others need to be considered: Most of those steps can be automated, but there are some details which need to be considered: Say "yes" when asked if you want to replace it app from /Volumes/SomeNameHere/ to /Applications/ app inside the /Volumes/SomeNameHere/Ĭopy the. dmg (which will then appear in /Volumes/SomeNameHere/)įind the. Many Mac apps come in ".dmg" files, and require the same set of steps: A shell script to work with Hazel to automatically install apps on OS X.
