The log file doesn't show any kind of error. This can mean one of the following:
- You are running out of disk space. Please check with your host. Do note that on hosts with "unlimited" or very large (in the dozens or hundreds of Gb) of disk space you are usually allocated a much smaller quote –usually 100Mb or 1Gb– and you have to request them to extend your quota when you reach it. On such hosts you will get a backup failure when you have reached that quota even though the hosting control panel may report something like "1 out of 300Gb used".
- You have a browser issue. Please try using a different browser, e.g. Chrome. FWIW I am also a Mac user and have confirmed that Akeeba Backup works just fine with the latest versions of Chrome, Safari, Firefox and Opera on my Mac. However there is also the possibility of having installed an application (usually: a firewall or an antivirus) or a browser plugin which interferes with the backup. It's best to try the backup from a completely different PC, connected to the Internet with a different ISP to determine if it's something on your computer.
- You have a Javascript error caused by a third party plugin. When on the backup page press CMD-ALT-I (Command, Alt and i) at the same time. It opens the Web Inspector window. Click inside that window and press CTRL-5. If there are any errors on the page they should be listed there.
If all else fails please post back so that I can make the ticket private and arrange for a way to have me take a look directly on your site.
