Offer your head of the Mac Club friend a few beers as a guest to give you a hand. A nice social time on the patio maybe!!

Sounds like a plan

You can, as Patrick said, download the installer, cancel it when and if it starts, then use something like DiskmakerX to create a bootable installer USB stick. Then backup, boot from the USB Stick, install the OS, restore from the backup. I didn't suggest that first because it really doesn't save any steps in the long run. The advantage is that if it doesn't work for any reason, you can still boot from the USB stick to try again.

Actually, I've never bothered using any DiskmakerX type utility or USB flash drive.

I've just moved the OS X installer to an "Install Stuff" folder I keep on my hard drive and then just used it from there to install the OS X version onto another Mac volume or just copy it over and then run it.

I never had any problems doing it that way.

If he’s got something bootable, that works. But a brand new drive won’t boot. A CCC clone would boot and let you do what you suggest, but then one MIGHT have to mess with boot settings later. I think not, but you mentioned it.

When using either Internet Recovery or installing from USB do I have to install original OS (Snow Leopard) and then later upgrade to High Sierra?

Or can simply install High Sierra?

When I wanted to download High Sierra from itunes on my MacBook it showed the message it is not possible because I have 10.6.8

Is there any other way to download it ?

upgrade to El Capitan first, then High Sierra.

Hello guys,

I just would like to thank you all for your help here. I managed to upgrade my MBP and I can see improvement in speed which is great.

I am still on Snow Leopard and as I mentioned in my earlier post I am happy with it. However more often I have slight issues with apps I use and that they cant be used on Snow Leopard. For example Chrome, Picbackman and couple others. This is basically the only reason I would like to upgrade to Sierra or High Sierra.

But I would like to also ask if there is any significant improvement in performance when switching from Snow Leopard to High Sierra?

That is a big leap, going from Snow Leopard to High Sierra. Maybe you should try El Capitan, https://support.apple.com/en-us/HT206886, and make a 60-80gb partition to install it onto so you can test it before going full speed ahead to High Sierra.
