can i jump from 10.7.5 to 10.8.5

Yes, you can.

Upgrading to Mountain Lion

To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase a redemption code at the Online Apple Store: OS X Mountain Lion. Mountain Lion is $19.99 plus tax. Use the code to redeem a download of Mountain Lion from the App Store. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

Not especially, but you should still back up the computer before proceeding.

It means that there are no risks beyond those typically involved in upgrading; specifically, those are that you may have software installed which is incompatible with the newer OS, and a problem may occur during the upgrade and result in the loss of data.

He means there is not especially any harm in jumping. That was the way you expressed your problem. I simply stated that you could make the jump. Neil was stating there was no harm in making the jump. Different ways of saying the same thing. 🙂

What Mac do you have? The pre-2006 Macs this forum covers cannot run any higher OS than 10.5.8.

Click on the App Store icon in the Dock, not iTunes, go to the main page, click on Redeem under Quick Links, and supply the code.
