can I upgrade directly from OSX 10.7.5 to Sierra?

I currently have Mac OS X Lion 10.7.5 (11G63), and I want to know if I can upgrade directly to the new OS Sierra.

Yes, as long as your MacBook Pro meets the specs for Sierra. It must be a mid 2010 or later model.

I've got the same operating system and last night I tried downloading the Sierra update. As a result I've lost everything and all attempts to reboot(?) using my original 10.7.5 system have failed miserably. I've been trying to put things right for over 18 hours and I'm at my wits end! I've scanned Apple support for anyone that seems to be in the same boat but can't find anything or anyone to help. It's a nightmare.

What, specifically, makes you think you have "lost everything?"

 

In other words, please explain what you saw while you installed Sierra and what you are seeing now that it is installed.

Why don't you start at the beginning and tell us all, especially the 'lost everything' bit

I'm not very techie so please bare with me chaps.

 

First up I went to the App Store and hit the update button. After 2-3 hours the process finished and failed and I was left with a grey screen. From that I ended up on 'Mac OS X Utilities' and the four options that come with it. I ignored the Time Machine option has I hadn't backed up my files (at least I don't think I did/have) and duly clicked on 'Reinstall Mac OS X'. After following the instructions and waiting umpteen hours for the process to finish it ultimately ended in failure. I've repeated that process several times over the last few days and it's failed everytime. Because of these failures and in desperation I opened 'Disc Utility' and hit every button available, 'verify', 'disc repair' etc, in the hope it would fix things, alas, it didn't. I've since gone back to and repeated the 'Reinstall Mac OS X' process dozens of times without success.

 

Failing is bad enough but having to wait several hours for the download to finish before it does is soul destroying.

I too am trying to upgrade from 10.7.5  ( OSX Lion to Sierra  ) .    My attemtps to upgrade have also failed .   I was previously on El Capitain when my disk drive failed.   

 

I put in a brand new drive ( with the machine connected on a wired connection to the internet ) , pressed  'cmd-R' keys with the power button.  The machine picks up the new drive with nothing on it, goes straight to Apple gets the utilities , you can then download OSX.  Unfortunately you get OXS 10.7.5 ( OSX Lion ), not Sierra or even El Capitain,  but at least you  get your machine back ( if not your data ) .

 

Subsequent attempts to upgrade from Lion to Sierra ( or anything else ) have failed ( machine 'failed to download...' or similar message ) leaving the machine in a state of limbo.   I am left with having to repeat the exercise   with CMD-R to get OSX Lion back on .  

 

When this happened ,  I also had to take the new drive out, put it on a USB connection to a windows machine, use the CLEAN command within the DISKPART utility  to clean the new disk drive ( which had the failed attempt to upgrade to Sierra  ) .

 

I am left with a working machine that does OSX lion ( 10.7.5 ) but no answer as to an upgrade. I 'd love an answer to this.

I don't know why your upgrades fail, but when you buy a bare hard drive, they are not formatted in any way. You must format them before you can used them. You could have done that in Recovery using Disk Utility, but as you found Diskpart did it too.

 

Some things that result in failed downloads are incorrect system clock or bad RAM.

You can also try restarting your modem and router.

It says for macbook, late 2009 or newer.  By the way, technically speaking it says the requirements are OSX 10.7.5 or later, 2 gigs of RAM and 8.8 GB of available storage.

 

My 13 inch macbook is from early 2008 with OSX 10.7.5.  It has 4 gigs of RAM and a 1 TB hard drive with plenty of space available.  I added the RAM of course and had to change the hard drive.  Do you think it's worth a shot to try and upgrade to Sierra?  I don't want to screw up anything.  It runs relatively well.  The fan gets a bit noisy at times and sometimes when I run firefox it's a little buggy but safari runs pretty well despite sometimes not being able to put videos into fullscreen sometimes but not all the time.

 

My main issue is that I cannot sync my iPhone SE to my macbook since the version of iTunes is not compatible.

 

Can anyone tell me if they have successfully upgraded to Sierra from osx 10.7.5?

Your MacBook is too old for Sierra, install El Capitan

Where do I get El Capitan? It's no longer on the App Store.

So I tried getting El Capitan from the App Store but it wouldn't let me download it.  My computer is not supported.  I don't understand cause technically I meet the requirements.  The next step up is Mountain Lion but I would have to pay for that and I'm still technically not supported for it.

By the way, technically speaking it says the requirements are OSX 10.7.5 or later, 2 gigs of RAM and 8.8 GB of available storage.

Technically, these are the requirements for El Capitan (which your Mac does not meet in any way):

Upgrade to OS X El Capitan - Apple Support

Can your Mac use El Capitan?

OS X El Capitan requires one of the following Mac models and versions of OS X. It also requires at least 2GB of memory and 8.8GB of storage space.

  • iMac (Mid 2007 or newer)
  • MacBook (Late 2008 Aluminum, Early 2009, or newer)
  • MacBook Pro (Mid 2007 or newer)
  • MacBook Air (Late 2008 or newer)
  • Mac mini (Early 2009 or newer)
  • Mac Pro (Early 2008 or newer)
  • Xserve (Early 2009)
  • OS X Yosemite v10.10
  • OS X Mavericks v10.9
  • OS X Mountain Lion v10.8
  • OS X Lion v10.7
  • Mac OS X Snow Leopard v10.6.8

 

The requirements for Sierra are slightly more restrictive, and the requirements for Mountain Lion are the same as El Capitan. OS X Mountain Lion system requirements - Apple Support

Can anyone tell me if they have successfully upgraded to Sierra from osx 10.7.5?

Lots of people have, but the OS isn't your problem. It is your hardware. You don't have a 64-bit EFI.

Because of that, your Mac isn't even capable of running Mountain Lion. 10.7.5 is as far as that Mac will go.

The processor I have is a intel core 2 duo 2.4 GHz 64 bit processor.  I did add extra Ram which now adds up to 4 gbs of ram and a 1 TB hard drive.  What is an EFI processor?

EFI is not a processor. It is the Extensible Firmware Interface. Windows computers use BIOS. Same purpose. It interfaces between the hardware and the OS. You must have a 64-bit EFI to use anything beyond Lion.

There is no way to upgrade it.
