I am running OS 10.4.11 on Intel Mac Book. Can I go directly to Lion?

Hi, and thanks for using JustAnswer.

Add this page to your Favorites/Bookmarks first, so as to get back to me anytime later on, if needed.

It's not possible as you download Lion (OS X 10.7) from the AppStore which is not present in OS X 10.4.
Customer: replied 5 years ago.
App Store? That's not what I would do. I would go purchase Lion from Apple and install in on my computer now running Tiger. I never said anything about downloading anything. I just want to know if I have to FIRST go to Leopard then to Snow Leopard and then to Lion - or if I can go directly from Tiger to Lion. Thanks.
Expert:  Mac Tech replied 5 years ago.
Sorry for the confusion.

Yes, you'll need Snow Leopard, which has the AppStore, which is the only way you can obtain and install Lion (other than purchasing a Mac with it pre-installed).

Hope that helps.

One last confirmation then I will accept. So I must get Leopard, then Snow Leopard?
Expert:  Mac Tech replied 5 years ago.
Yes, Snow Leopard is an Upgrade.
Expert:  Mac Tech replied 5 years ago.
I stand corrected, you do not need Leopard before Snow Leopard.

See this from the Apple Store web site:
To upgrade your Mac to OS X Lion, you must be running OS X Snow Leopard. If you have OS X v10.5 or earlier, purchase Snow Leopard now and install it on your Mac. Then buy OS X Lion as a digital download from the Mac App Store

Also, make sure your Mac specs are compatible. There is a rumour that Apple will be selling Lion on USB. I'm not sure what the requirements will be for this.

Lion/101.7 System requirements

• x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)

• At least 2GB of memory, (I say 4GB)

• Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed

• At least 4GB of disk space for downloading, (I say 40GB at least)


Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).


Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.
