MacBook Pro :: Unable To Reinstall OSX Mountain Lion
Jun 2, 2014
I recently returned from a weekend long trip. My mom had used my Mac Book Pro (December 2012) on the guest account. When I opened it on Monday it was unresponsive, and the screen only showed the dock. I rebooted, but the result was a white screen with a flashing folder with a question mark. I followed instructions on the forums, and used command r. Now I am stuck. I didn't back it up with time machine, so that option (Of the 4) is out of the question. I'm using the safari one now. I can't modify or delete my disks for the Disk Utility Option, and am unable to select a disk to reinstall Mountain Lion on. Long story short, I seems my computer is having problems with the disk.
I just purchase a used macbook And I was trying to delete the previous owner account and info, I deleted de OS X mountain lion and when I try to reinstall it a message shows "This item is not available, try again later"... I have try several options and nothing seems to work.
I had a crash on my Macbook Air MD231 - Mid 2012, and my system won't boot, and unfortunately my friend erase my partition from disk utility.
Now I have three question
1)my internet speed is very low, for re-installing I have to download all of the OS X 10.8 from internet? or I can download it and install it via USB port?(how??)
2)I have to select this option ? "re-install OS X" , and what about size of that? (for example 4.2 Gb)
3)after installing , is there anyway to restore my dada? unfortunately I have not any backup right now, after I turning my Mac on, it's automatically going to repair mode...
I inadvertently deleted my OSX 10 Lion operating system on my Mac Mini -- tried redownloading it but continually received an automated response saying something like ".... unable to download the software, try again later" That is not an exact quote but close. I tried several times to download the software but always received the same message. I did verify that WIFI was up and working properly on my separate laptop.
Info: Mac mini (Mid 2010), OS X Mountain Lion (10.8)
I have purchased Mountain Lion from the App Store. When I try to download i get a message stating that it cannot be downloaded. My Mac Book Air has the correct specifications needed but Apple won't let me download the software.
I cannot connect to a website that I have been using happily for months. The connect request times out. I don't know what to do. The website owner says there is no problem
I have just upgraded to Windows 8 and I get the following message when trying to start Windows 8. "Unable to load the Parallels driver / problem ID 352"...I have tried running the Disk repair permissions and disk utility permissions and reloading Parallels 7 as suggested by Parallels.I am running OS X 10.9.4
I have been unable to send emails from my domain account due to it being blacklisted. I am not a spammer but think my account was used recently by one. I have been unable to find out how to get my ISP de-listed as I have passed from place to place with no-one taking responsibility.
This is the error message I get "the sender address was rejected by the server [URL]`. The server response was: ATLAS(2502): 86.186.228.20 is blacklisted and not authenticated. Please request delisting via the following link: [URL] .... Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent."
I am having problems ejecting the external hard drive that I use to back up my laptop. It is a 2012 MacBook Pro running Mountain Lion OSX 10.8.5. My external hard drive is a WD 2 TB My Book Studio. I use it to back up my laptop with Time Machine. Every time I try to eject my disk now I am told that "The disk (Diskname) wasn't ejected because one or more programs may be using it." I have tried some solutions like to stop Spotlight from indexing the disk and to try and turn off TimeMachine, but neither of these worked. The only thing that has worked so far is to log out of my user name and log back in with a guest user and eject it from there. This takes up a lot of time and is ultimately not really a sustainable way of working on my computer.
I just received my new Mac pro at work and is trying to install Mountain Lion as the OS instead of Mavericks but it seems impossible. Every time I try to boot up on a bootable 10.8 installation drive I get the no entry sign. I even cloned my old MacPro and tried to boot from the external drive, I still get the no entry sign.
I tried booting from a thunderbolt, USB and even super drive, with no luck.
I need to install 10.8 because Mavericks doesn't work with Active Directory in my company, it just hangs the system every time, we've tried many different ways to fix this but it just seems to get worst.
Any way I can downgrade a 2013 Mac Pro to 10.8?
Info: Mac Pro, OS X Mavericks (10.9.4), OS X Mountain Lion (10.8.5)
I haven't been able to reinstall OS-X on it at all. It takes 45 minutes from the time I say install to the time it gets only 1/10 of the bar across of the installing part and then fails.
I am able to format the HD, and partition it. This HD came out of another laptop of mine that I sold and was working fine. When I first tried this and did a time keeper restore, the laptop kept freezing and it took 5 hours for it to restore. Now I can't get OS-X installed. So I am a bit confused what is going on here.
I wanted to reformat my computer to "factory setting" and inserted the usb that came along with the mba i bought. Clicked install and restarted and followed instruction.
When the installation was done and computer rebooted, i didn't see any changes at all. Everything was exactly the same.
just recieved my refurbished macbook air (2011) 2 weeks ago.Does it qualify for free upgrade to mountain lion ? The website only talked about "qualifying new mac system set..."
I accidently deleted some file on my computer that wouldn't let me start up my MacBook pro, 13 Inch, so I had to press Command- R at start up (brought me to Lion Recovery) and I choose reinstall lion and I started it yesterday morning and all day and over night. It's barely half way through and it says "148 Hours Left" which is crazy.. Should I just wait? is this normal? what do I do?
I was about to buy Lion so I can start using the extra space I purchased on Iclouds but I noticed that Mountain Lion is coming later this summer.Can I wait and simply install Mountain Lion without ever getting Lion?
when mountain lion will release this year if I upgrade my Lion OS to new Apple's new Mac OS what will happen to recovery HD partition? They said my Lion OS will be gone and everything will be Mountain Lion. I bought this Macbook pro late 2011 and its running Lion OS with recovery HD.
I purchased my computer 4 months ago and have had nothing but troubles since. When I bought it I think I downloaded OS X Mountain Lion for free, either that or my computer came with it. After several attempts from Geek Squad at Best Buy to fix my computer, they finally reset the computer back to factory settings. Now I do not have OS X Mountain Lion and cannot figure out how to download it for free (Because if I had to download it in the first place, I downloaded it for free), and I do not have iphoto. This is my second Macbook, and the first one I remember having to purchase ilife to get iphoto.
I saw the new Mountain Lion preview on WWDC 2012 today, and I am planning to upgrade ML when it comes out. I was just wondering if all the data and apps get transfered into the new ML OS when I upgrade from my Macbook Pro with OS X Lion?
Info: MacBook Pro (13-inch Late 2011), Mac OS X (10.7.3)
