Mac App Store re-installation

I did system restore for OSX 10.9.5 using Time Machine. Unfortunately, I did not back up the application, which end up no application was installed after restoration including the MAC App Store. I try to get it installed online, however, I cannot view MAC serial no in System Information. How to install back the MAC App Store?

Do a backup. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Then re-install the OS.

OS X Recovery (2)
If successful, use Setup Assistant to restore your backup.

If you have problems with your Mac you use Lion Recovery
However, you can create your own installation disc > How to create an OS X Lion installation disc | MacFixIt - CNET Reviews
Since Lion came pre installed on your Mac, the App Store doesn't not recognize that as a purchase so you if you want to re download Lion to create a boot disk you will have to pay for it. You can then re download Lion on all your authorized Macs for free.

Problems with the mac app store login/ yosemite installer download

I am trying to download the yosemite installer from the mac app store, but can't seem to log in. I receive no error message. What could be causing these issues? I am using a MacBook Pro with OS X 10.6.8.

Based on the numerous posts regarding iTunes and the App Store, there appears to be an issue at Apple's end. Although Apple has not provided any indication on the cloud status page.
Do not change your settings.

"Download the OS X Installer app from the Mac App Store" - where to find it? A search doesn't bring any result...

I want to create a bootable USB drive for Yosemite. The support site suggests to ""Download the OS X Installer app from the Mac App Store" prior the creation. But where to find it in the App store? Any search combination does not bring a meaningful result....
Thanks guys.

Thanks Matt, understood. It was my fault, just simply thinking, there is an App called "Installer"

It seems that the installer on the Mac App Store is still OS X 10.9.3

I downloaded the full installer app from the Mac App Store today.
The version written on the Information Column is 10.9.4.
However, I checked the md5 of the InstallESD.dmg only to find that it is the same as OS X 10.9.3's InstallESD.dmg.
Hence, it seems that the full installer app on the MAS now is still OS X 10.9.3.
Is there anyone who encountered the same problem?
Here is the screenshot of the md5.

Does the InstallESD.dmg contain everything that gets installed? I thought there were other packages that were external to the installESD?
Do you need to compare every file?
FileMerge in the developer tools does this visually.
Or use find with md5…
find "/Applications/Install OS X Mavericks.app" -type f -exec md5 {} \;
# big list of md5's...
You could just compare packages.
find "/Applications/Install OS X Mavericks.app" -type f -name *.mpkg -exec md5 {} \;
I suspect the installer also downloads updates, but it's not clear if this is automated or if it is only done in software update after the install, it seems like the latter.
Also bear in mind lots of caching goes on with massive distribution systems like the App Store updates, you may want to give it a few hours (or days) to allow caches to be fully renewed, or try another network connection if possible, some ISP's can try to be aggressive about DNS or other caching.

How can I copy installation/setup files of an App downloaded from Mac App Store?

I just purchased and downloaded Xcode on my Macbook Pro and now want to install the same on my MacBook Air and iMac but I don't want download them again and again. Isin't their anyway by which I can copy the installation/setup files of that App and paste it on another Mac and use my iTunes account credentials to verify the App with Apple servers, so that they know it's legit install. And also keep the copy as backup so that, I can install that App again after I format my computer or use it for future use.
I live in a third world country and aren't blessed with high speed and unlimited bandwidth connection.

The Mac App Store remembers all apps you purchase with your account. Apps you purchase and install from Mac App Store can also be copied to an external hard drive, USB Flash Drive, CD/DVD, or backed up via Time Machine.
If you save a copy of an app to removable media (such as an external hard drive) or file share, simply drag the app back from its storage location to your Applications folder. When you open the restored app for the first time, you may be required to sign in with the Apple ID account that was used to purchase the app.

That should work... as to whether the printer driver will work, that's another question.

Unable to login in to Mac App Store using valid account.

I recently inherited a spare MacBook Air from my wife (who got a new one). I deleted her user account, and set up a new admin user account for me. The machine is running 10.7.5.
Now, I am absolutely unable to login to the App Store. I am using my valid Apple ID -- for example, the same Apple ID that I used to gain access to this very forum. System Preferences accepts my ID. iTunes accepts my ID. BUT the App Store will aboslutely NOT respond. It will not load. I get the red "connection failed" alert, and then after several tries it doesn't respond at all.
It doesn't give any option to switch users -- perhaps once the original owner has used the App Store, the computer will never again allow anyone else to use it? It doesn't say that there is another user logged in. There appears to be no way of deleting and reinastalling the App Store. There is no cache file I can find to be cleared. There is no preference option. There is no information. There appears to be no way of fixing this at all, short of wiping the hard drive and reinstalling the operating system. Is that what I have to do? WHY IS THIS SO HORRIBLY DESIGNED? And why is there no support short of the forum? I hate this about Apple (despite being a long-time Apple evangelist and OSX devotee).
Thanks.

The first thing you should do after acquiring a second-hand computer is to erase the internal drive and install a clean copy of OS X. How you do that depends on the model. Look it up on this page to see what version was originally installed.
If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard installation disc, which you can get from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. I suggest you install as much memory as it can take, according to the technical specifications.
If the machine shipped with OS X 10.6, you need the gray installation discs that came with it. If you don't have the discs, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To boot from an optical disc, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
If the machine shipped with OS X 10.7 or later, it should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
Once booted from the disc or in Internet Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive, which is what you should do.
After partitioning, quit Disk Utility and run the OS X Installer. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
You should then run Software Update and install all available system updates from Apple. If you want to upgrade to a major version of OS X newer than 10.6, buy it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Apple customer service has sometimes issued redemption codes for these apps to second owners who asked.

Problem with Resuming and Installing Apps Purchased using Mac App Store

Recently I have been trying to download and install AeroFly FS which I purchased from Mac App Store (17GB) and with my internet connection it take some 4-5 days to download that.
I have 2 problems.
1) Resume download don't work if I happen to reboot my macbook pro for some reason after pausing the download before the reboot. When I reboot and try resuming the download... the resume button changes to install, and the download start afresh, I technically lost all my previous downloaded data.
2) The app was 17GB ( I guess thats the installer), and I had some 25GB left after the download completed. But it gave an error saying while installing that not much disk space. So I moved/deleted many item on my drive and got the disk space to some 37GB Free. But it was still giving the same error of not much disk space.
So, I thought the new avaialable diskspace was not accounted for. So, I rebooted the macbook. And to my agony, I found the roboot wiped out the 17GB installer I managed to download from Mac App Store.
So, far i have wasted almost more than a week trying to download and install this app. Now, I am re-downloading it for the third time.
Any Help will be highly appreciated.
Any Tips on how I can move the installer once it sdownloaded to my external HDD, and where can i find this installer which App store downloads?
Regards,
Sapam

Hi ...
37GB of free space is not enough.
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 20% free disk space.

How do I download an app from the Mac App Store but not install it yet?

How do I download an app from the Mac App Store but not install it yet?
Can I simply download it and not install?
What if the App gets updated before I download it?
Why? Well, I am very busy and wish to install at my leisure even though I have purchased the App (required at a specific day in the month in order to appear on my business accounts).
Thanks.

There is a difference in what Kappy stated and what you stated. A major paid upgrade (v2.x to v3.0), yes, costs money, as it would in any other delivery stream. Updates (v3.0 to v3.1) to a a major version are free.
Most apps sold through the Mac App Store (MAS) are the type that use the simple drag & drop installation. Those are downloaded directly to the designated apps folder and installation is done. Large pro-type apps download an installer to your Apps folder. Those you can install at your leisure. The MAS does not have a lot of apps using this type of installation.
Be sure to always backup your MAS purchases, because there is no guarantee that the app will always be available for download in the future and it is your responsibility to archive copies.

Mac App Store updating apps on _other_ drive :-(

A little background first - wanted to not just jump right in in upgrading to Mountain Lion (10.8.0), so I got (same brand) external USB HD, formatted it, installed Mountain Lion on that. (With some assistance from Apple Support...) I have moved most all my apps and documents over to the (external) ML drive (500GB). Also have many apps bought through MAS and installed on the ML-500 external drive. When I want to use ML, I boot up from it; other times, I will boot up with Snow Leopard (10.6.8) on the internal drive (320GB) to use a few apps where I haven't had all their docs transmogrified to 10.8-compatible apps. Most of the time now, things have been workable and fine.
In the past couple of days, I have discovered that apparently when I had logged into the MAS to update my ML-compatible apps, the MAS (unbeknown to me) updated the older (10.6.8-compatible) apps I had there, including iWork '08 (which had been updated as far as 10.6.8 updates would take them).
So now, it appears (since version numbers are the same for the Numbers, Pages and Keynote apps between the two OS drives) that I have (non-10.6.8-compatible) apps on the Snow Leopard (internal) drive, that won't run when I start up with 10.6.8. The icons on the 10.6.8 drive for Numbers, Pages, and Keynote (which were inside an iWork '08 folder, inside the Applications folder, on the internal/10.6.8 drive) have the 'not' circle and line across them when I view them running from the Mac OS X 10.6.8 (internal) drive. Haven't checked other MAS-downloaded 10.6-compatible purchased apps, so there may be more 'over-updated' apps...
I know that I have my original iWork '08 DVD (and likely, can go back through my Time Machine backups to try to find my latest versions under 10.6.8) and can re-install (and then install all the updates since then under 10.6.8) to get them back, but I would think - since OS X install discs check a drive for the system version number before installing - that MAS would be setup to FIRST check what the OS X version for a drive with Pages/Numbers/Keynote/other Apple non-system apps, before installing a version over an app (that renders it useless for that version of OS X).
Even though I can possibly (with much time/updates/re-installs) get my earlier apps back on the internal drive, my concern is - how can I stop MAS from once again 'over-updating' those apps? If the MAS can check and tell me that an app I want to download requires 10.7 or 10.8, it would seem to make equal sense for it to check first whether I have (on different drives) 10.6.8 and 10.8 versions of the same app, and ONLY update the most recent one, NOT all of them.
Makes me wonder if Apple thinks that NO ONE out here is running separate partitions or drives with different operating systems for different app needs. I am very sure that there are specfic-market applications out there that companies, laboratories and others need to get tasks done (and for which there is not yet so far a Lion or Mountain Lion-compatible version), so those people/companies/etc. are likely running different OS partitions or startup drives. So WHY does the MAS not check first? Or more importantly, is there some way to stop/limit the updates so ONLY one drive gets updated?

Hello Dahveed, thank you for your answer but this is not good at all. These are not core applications. For instance i want all my games to be on external Hard drive (for instance X3 is about 8 Gb). For having my home folder on external HD this is not good at all too.
Why i should change my way to work and manage my files just for a logical problem ?
Furthermore, the Mac App Store app detects i have the application already installed even if it is on external HD, so there are only 2 solutions : there is a bug into the mac app store application for managing apps OR this is pretty bad for users to have the apps sequestrated into the home folder.
You can see even iTunes with the music rights management system is able to let you have musics managed by user.
Do you have another solution ?
Thank you

Mac App Store on my Macbook Pro

Why can I not find my Mac App Store even though the software is updated? I bought my Macbook Pro in 2009; is it outdated?
I'd really, really appreciate your help.

The only way to install App Store apps on your other macs is to have them running 10.6.7 so that you can access the App Store.
The installer for Snow Leopard is only $29 so it isn't to bad as far as cost, plus you will get all of the extras from 10.6 on your MBP.
You can get it here at Amazon.com http://tinyurl.com/6cd64ba or from the store here at Apple.com.
