Macintosh: Upgrade to Lion from Leopard


1) I have a MacMini
- The Operating system is Mac OS X 10.5 (Leopard)

2) I want to upgrade to Lion (Mac OS X 10.7)

3) And I just want to buy One license
- I will buy the license to upgrade to Lion only ($ 29)
- Then, I will do the "clean install" at the above machine

4) My question: Is the above approach technically and legally OK?

I believe the Apple web sites says that won't work.  You would have to buy the full install if you want to skip a version.  See here: http://www.apple.com/macosx/how-to-buy/

Apply all updates to get the app store. Buy the version the app store says is correct as it knows the os you are running. Follow these instructions to make a DVD
Boot that DVD and use disk utility to reformat as 1 partition.
Install lion clean.

Hi aarontomosky,

1) Per your above approaches ....

- I have to upgrade from Leopard to snow Leopard firstly (buy License #1)
- Then from Snow leopard i will update to Lion (buy the license # 2 --> $ 29)

2) So I can not just buy One license (to upgrade to Lion)  and do the Clean install, right?

3) Clarify your understanding please

You have to purchase Snow Leopard (OS 10.6) for $29.

Then download and install the free update from 10.6 to 10.6.8 from:  http://support.apple.com/kb/DL1399

Then go to the App store and download and install Lion (OS 10.7).

Total cost $58.

Hi All,

1) It seems that strung is correct that I can not "bypass" from Leopard to Lion and pay only for one license (I have to pay 2 licenses from Leopard to snow leopard and from snow leopard to lion --> total: $ 58)

2) If other experts have different opinion related to #1, please post it back

I think @strung is correct.  I can't find anywhere that you can get a Full Install version Lion.  The two step upgrade is the only path I see.  I don't even see a listing for any CDs at all for Lion.

Hi all:

1) This is the summary (of this discussion):

2) I have to buy 2 licenses:
    * First: To upgrade from Leopard to snow leopard --> $ 29
    * Second: To upgrade from snow leopard to Lion --> $ 29
    * Total cost is $ 58
    * This is no other Option; This is the only Path that I should take!

3) However, I am still be able to do the Clean Install (for the Lion)
   * First : To upgrade from Leopard to snow leopard (I will buy the License and get the installation file for it)
   * After the MacMini is at the Snow leopard; I will download or buy the Lincense #2 (To upgrade it to Lion); this installation file will be in the Application folder; I will BE ABLE to do the CLEAN Install following this link  (suggested by aarontomosky) ---> http://lifehacker.com/5823096/how-to-burn-your-own-lion-install-dvd-or-flash-drive

4) If any experts have different opinion or do not agree with this summary, post it back please


Leagally, you are totally correct in that you will need to buy two licenses, one Snow Leopard (only available on DVD) and one Lion (only available via download) to follow Apple's license agreement for Lion.

Technically, though, you do _not_ need to upgrade to Snow Leopard first if you will make a clean install of Lion. A clean install from an already made Lion-DVD will work as long as your computer meets the system requirements of Lion.

So if you have another computer with Snow Leopard or Lion on which you can buy, download and burn your Lion DVD then your good to go - technically - for a clean install of Lion on your Mac mini.

Again: You still need a Snow Leopard license to be OK leagally, but not technically.

Best Regards,
Jens Helander
