Mountain Lion upgrade question

Hello, so i wanted to upgrade to Mountain Lion, and would just like to know the best way to back up my copy of lion if i need to downgrade, i already have a time machine back up. Also if i do need to downgrade, what is the best way to do so?

A very good method to backup is make a bootable clone of the internal hard drive on an exernal drive...that gives you boot options should you want to switch back and forth between the operating systems.  You can check the offerings of sources such as the Mac specialists at OWC for great ideas.

  • Can't login after Mountain Lion upgrade (Network accounts are unavailable)

    I performed a Mountain Lion upgrade on a 2011 MBP running Lion this weekend. The Mac may have been set up to connect to an AD server with my user account, but I thought I had disabled that months ago... aparently not. I performed the upgrade at home not on the corporate network.
    On first bootup after the Mountain Lion upgrade I'm stuck at the login screen unable to login with my local account or the admin account. I get the "red dot" next to the username field with the "Network accounts are unavailable" pop up. I'm plugged in to the ethernet network at work now... no luck.
    I tried booting into the repair disk and repairing disk permissions. Still no luck.
    Any ideas? I'd happily do a fresh install but I need to get a handful of files off the machine first.

    No worries with the basic questions... it's important to cover all the bases. Thanks so much for the input.
    - I'm trying to log in with the same username I would use to ssh in... so yes.
    - I don't know if the account was a mobile account. The Mac was given to me configured about a year ago, configured to be on the domain. I since have used it on and off many networks without considering it was set up to be on a domain.
    - Never had a problem logging into the machine before the mountain lion install, although to be honest it was very very rarely ever rebooted.
    - I've plugged it into ethernet and let it sit for quite some time. It's still telling me Network accounts are unavailable and I'm unable to login with my personal or admin account.

  • Time Machine best practices after Lion to Mountain Lion upgrade

    I've made the upgrade from Lion to Mountain Lion and everything seems to be OK.
    I have been using Time Machine for backups since I deployed my first and, so far, only Mac (Mac Mini running Lion) in 2011.  I run my TM backups manually.  Since upgrading to Mountain Lion, I have not yet kicked off a TM backup, so my questions involve best practices with TM after an upgrade from Lion to Mountain Lion:
    Can I simply use the same drive as I use currently, do what I've always done, start the backup manually, and TM handles gracefully the new backup from the new OS?  
    At this point, since I have only backups to the Lion system, what I see when I doubleclick on the Time Machine drive is a folder called “Backups.backupdb”, then a subfolder called “My Mac mini”, and then all the backup events.   Nothing else.  What will I see once I do a backup now, after the Mountain Lion upgrade?
    If I for some reason needed to boot to my old Lion system (I cloned the startup disk prior to upgrading to ML) and access my old Lion backups with TM, would I be successful?  In other words does the system know that I'm booted to Lion, so give me access to the TM backups created under Lion?   Conversely when booted to the new Mountain Lion system, will I have access only to the backups created since the upgrade to Mountain Lion?
    Any other best practices steps I should take prior to my first ML backup?
    Time Machine is a great straightforward system to use (although I have to say I’ve not (yet) needed to depend on it for recovery...I trust that will go will when needed) but I don't want to make any assumptions as to how it works after a major OS upgrade.
    Thank you for reading.

    1. Correct. If you want to downgrade to OS X Lion, your Mac will still keep backups created with OS X Lion, so just start into Internet Recovery and select one of the backups made with OS X Lion. If you don't want that Time Machine backs up automatically, you may need to use TimeMachineEditor.
    2. After making a backup with Mountain Lion, it will be the same, but with a new folder that belongs to the new backup you have created.
    3. See my first answer.
    4. One advice: when your Time Machine drive gets full, Time Machine deletes old backups, so maybe it can remove all your OS X Lion backups. However, I don't think that you would need to go back to OS X Lion.
    If you have any questions apart from those, see Pondini's website > http://pondini.org

  • Does the OS X Mountain Lion upgrade include iPhones and iPads?

    This is probably a dumb question, but does the OS X Mountain Lion upgrade automatically include iPhones and iPads?

    I don't know quite what you mean. Mountain Lion is for Macs and has nothing directly to do with iPhones and iPads at all.

  • I bought a Mountain Lion upgrade for $20 off the Apple site. I have four other Macs all under the same ID. How can I share the new OS with other computers. Or can I?

    I bought a Mountain Lion upgrade for $20 off the Apple site. I have four other Macs all under the same ID. How can I share the new OS with other computers. Or can I?

    You can share it with other Macs under your control (not your neighbor's).  You just need to be logged in under the buying AppleID for updates or to download again.
    Use this thread to find a method of copying the ML download into a USB drive to make other installations easier: https://discussions.apple.com/message/16639520#16639520

    Do you get this window when you hold down the Command+Option keys and launch iPhoto?

  • Enabled fonts not showing up in InDesign after Mountain Lion Upgrade

    After upgrading to Mountain Lion, fonts that are enabled in Font Book (Adobe open Type) are not showing up in InDesign CS5.5.
    However, if I go to Font Book and disable the fonts, then re-enable them...they will show up in InDesign.
    Anyone know how to fix this?
    Thanks!

    It sounds like a small glitch in your Mountain Lion upgrade. If you're just done an in-place upgrade (not a clean install) these things can happen.
    It sounds like you've found the workaround. But if you discover other problems with the upgrade, you should consider a clean install. Do a Google search on "clean install Mountain Lion" to find out how.

  • Downloading Mountain Lion upgrade from App Store failed

    I'm upgrading my wife's iMac from Snow Leopard 10.6.8 to Mountain Lion. Just tried to download the Mountain Lion upgrade from the App Store. I paid for it, clicked on the download, the little icon did it's fancy leap down to the application bar at the bottom of the page, and the item in the app store said it was downloading as well as the white bar beneath the icon in the app bar at the bottom of the screen. Nothing happened. I left the computer and came back about ten minutes later. The app store had crashed. Rebooted it. Tried the download process again. Same result.
    I paid about $20 for the system software upgrade so I would like, if possible, to use the app store item if I can. Is there a solution without a trip to the Apple Store to buy the system upgrade?
    John Kendrick

    Quit the App Store if it's open.
    Open the Finder. From the Finder menu bar top of your screen click Go > Go to Folder
    Type this exactly as you see it here:
    /Library/Preferences/SystemConfiguration
    Click Go
    Move the NetworkInterfaces.plist file from the SystemConfiguration folder to the Trash.
    Relaunch the App Store and try downloading Mountain Lion.

  • HT1338 For some reason I simply cannot find a button anywhere to purchase Mountain Lion upgrade software.

    I have been looking for the click button to purchase Mac OS X Mountain Lion upgrade.
    I have been going round and round and cannot find that place.  Please help.

    From what I've read on these forums over the past few months, it hasn't gotten any better. An electronic order from any company shouldn't take more than 12 hours for a system to respond to, but people have been waiting up to a week for their redemption code email to arrive. It makes no sense to me why it would take that long.

  • I only got second email for free OS X mountain lion upgrade

    I got approved for free OS X Mountain Lion upgrade but I haven't received first email that contain PDF file. but I got a email with password to open PDF.
    any idea?

    I received TWO OS X Mountain Lion Up-to-Date Password Emails, but no email with the PDF content code on July 27, 2012.
    The email said "If you did not receive an email from the OS X Mountain Lion Up-To-Date program with your content code, please check your spam filter settings for attachment restrictions and contact us at [email protected] to have this email and your content code re-sent."
    I checked my spam folder & didn't see anything. I emailed asking for the content code email to be resent, just like the email said. I got what I assume was an automated response on July 31, 2012 (4 days later). That email said:
    Thank you for contacting the OS X Mountain Lion Up-To-Date Support Team regarding your request to change the email address associated with your claim.
    In order to change the email address, please send the following information to [email protected]
    Your Claim reference number
    Original email address
    Revised email address
    Requester name:
    Requester address
    Requester phone number
    The reason I assumed it was automated is because the parts above in red were highlighted in my email. I emailed [email protected] again indicating that I just need the content code resent. I received the SAME automated email on August 2, 2012 (2 days later):

    Same email, just different parts highlighted.
    Apparently, email correspondence does not work since it thinks I want to change my email address. I'll have to call Apple Care directly to find out what is going on.

  • Since Mountain Lion Upgrade is my Internet connection very slow, Since Mountain Lion Upgrade is my Internet connection very slow

    Why is Safari so slow after Mountain Lion upgrade?

    I have a home Optimum wifi network with Boost connecting to an Airport, with a second Airport extending, and an Airport Express extending. I have a MacBook Pro, last year's model, two iMacs, a year old each, and an older iMac. (If necessary I can get all the models etc, but I just want to express the problem). The two new iMacs and MBP are running Mountain Lion. The older Lion.
    Since upgrading to ML my connection speed both over the wifi and directly connecting to the router has dropped from 30-50 down and 5 up to between 1-4 down and 4 up. I have had the cable folks here to test lines. We've swapped out the modem with a new one. I bought a new netgear N600. Everything led to the same result.
    Here's the odd part. When restarting the modem and plugging it directly into the powerbook, initial tests show 30-50 up and 5 down. But once you reconnect to wifi, lose speed, the re-connect directly to the modem the slowness persists directly connected to the modem.
    So I start suspecting Mountain Lion. BUT the older iMac cannot be upgraded to Mountain and is still running Lion and has the same issue. The equipment is in the same place it's always been. We've added no electronics that would be interfering with signals.
    Everyone is stumped and looking suspicously at the computer and OS. Please help. I'm beginning to hear the bing bong bing bong of dial up in my head.

  • Mountain Lion upgrade, plus App Store...

    Im going to be getting a Mac Mini sometime soon, (hopefully in the next few weeks) and was wondering the Free Mountain Lion upgrade, is that only for buying from the Apple online Store, or does it go for anywhere you buy the system new?
    Also i have bought the Numbers app on my iPhone 4, and also had the download for my iPad 2 as well for free, will this count on my Mac Mini from the App store, or will i have to pay for the app again when i get my Mini?
    Thanks
