For Mac:  You may come across this message:"Hightail Mac Express.pkg can't be opened because it is from an unidentified developer."


No worries, the way we can get pass this message is by going to the “System Preferences” on your Mac and clicking on “Security & Privacy” (House icon towards the top right.)

Once you are on the “Security & Privacy” page. Click on “General” and then you may see a message stating that the .pkg was blocked from opening because it is not from an identified developer and there will be an “Open Anyway” button.

If you are not given the “Open Anyway” option then click on the lock icon on the bottom left of the window. You may be prompted for your Mac password. Once you enter in your password, you will be able to allow apps downloaded from “Anywhere”.

Once “Anywhere” is selected, you will be able to run the .pkg file that was previously downloaded and follow the prompts in order to completely install the Hightail Express application.
