We have listed 7 Ways to Fix iPhone Keeps Asking for Password Issue.Mac OS X can similarly tell if an app came from the Store or not. If your iPhone is repeatedly asking you to input Apple ID Password, read this guide. In the Apple App store when I click on 'update' it prompts me for the password and has the e-mail address of the previous employee automatically filled in (and I can't. For example there's an update to Evernote.This is the key difference between MAS apps and non-MAS apps. In the list that appears, you’ll see a folder named _MASReceipt. Next, open the Contents folder. To do so, access the Contextual Menu for an MAS app and select Show Package Contents. MAS versions of apps: What’s the difference?To find the answer here, you need to peer inside an MAS app. Not so with Mac App Store apps.How exactly are MAS apps different from other apps? How do the App Store and Mac OS X treat the distinctions? What Mac OS X software handles recognizing these differences? Perhaps most importantly, if you have a choice between an MAS and non-MAS version of the same app, which should you prefer? Read on…Non-MAS vs.
![]() App Store Keeps Ag For Apple Id Mac OS X Can SimilarlyIf not, the app will not run. When you launch an MAS app, the app checks the receipt to see if your computer has been authorized to run it. Also referred to as a certificate file, this is the essential item for implementing copy-protection. Non-MAS apps will not.Inside the _MASReceipt folder is a file named receipt. Ios simulator for mac visual studioIf the result does not match the hash in the receipt, verification fails.” In other words, the receipt file is modified when you first install the app from the MAS this is what allows the app to validate and run on your computer.A developer has the option to decide the extent of receipt checking for an app. The last is to compute the “hash of your computer’s GUID. The first check is to simply look for the receipt. ![]() It will typically either trigger a message asking for your Apple ID/password or simply refuse to launch with no alert given.That said, there are reasons why you may yet prefer the MAS app. Most notably, after copying an MAS app to a different computer via the Finder, it likely won’t launch. For the most part, they will immediately and successfully launch, just as they do on the originating computer.With MAS apps, you will likely run into various copy-protection problems — even with freeware. The main one is that you can freely copy non-MAS apps to any other computer with no restrictions — especially so for freeware. MAS versions of appsAssuming you have a choice, there are reasons to prefer the non-MAS version of an app as compared to its MAS twin. The App Store only runs in Mac OS X 10.6.6 or later. MAS versions of appsThe App Store app and its associated software are installed as part of Mac OS X 10.6.6. Further, unlike software that requires a registration code, you can install MAS apps on any other machine that uses your Apple ID, without having to remember and enter a different code for each such app.Mac OS X requirement: non-MAS vs. Not unless you consider the advantages of the Mac App Store to be worth paying for the same app twice. Should you switch to the MAS version?No. There is a functionally identical version of the app available for purchase in the App Store. MAS versions of appsYou purchased an app prior to the MAS Store’s arrival. For Macs not yet running Mac OS X 10.6.6 (which only runs on Intel Macs), the non-MAS version of an app is the required choice.Re-purchasing: non-MAS vs. If you copy an MAS app from a Mac running 10.6.6 to an Mac running an earlier version of OS X, you will receive this message when you try to open the app.This becomes another reason to prefer non-MAS versions of apps (assuming they are available). The App Store will then allow you to purchase the app. If you truly want to switch to the MAS version, you have to first remove the non-MAS version (all copies of it!) from your drive. This is a protection against duplicate payment for the same app. If you already have a non-MAS version of an app installed on your drive, the App Store will list that app as “Installed.” There will be no option to purchase it. For example, the developer of Find Any File will continue to offer a free non-MAS version of the app. Of course, even without the MAS, a developer could charge for an upgrade.For now, some developers are sitting on the fence. When the next update is released, the only way to obtain the update will be via the App Store. This could happen if a developer decides to offer his software exclusively in the App Store. This could lead to you (mistakenly?) repurchasing software already on your drive.At some point, you may be “forced” to purchase software from the App Store that you already own outside of the Store. This was the case for me with Apple’s iWork software ( as I covered in my Bugs & Fixes article). If, for whatever reason, you want to save the older version, you’ll need to make a copy of the app first (and ideally compress it).Receipt-checking and multiple Apple accountsAs already stated, if you use the Finder to copy an MAS app to another computer, you will likely get a request to enter your Apple ID and password when you launch the app. Speaking of updates, be aware that installing a new version of an app via the App Store replaces the existing version. Going forward, I expect that he will eventually stop updating the non-MAS version.Techie note: How does the App Store know what apps are already installed on your drive? By checking for “bundle IDs,” as described more in this Macworld article. ![]() However, if you already have a copy of the app installed under one Apple ID, you will not be able to purchase it under another ID — because it will be listed as already Installed. It’s just that you can only track the app in the App Store when signed in to the Apple account that purchased it.To avoid this tracking hassle, each computer owner must purchase their own copy of the app (which, in most cases, is ethically what you should probably do anyway). The app will even run when logged into another OS X user account on your Mac. You only need to enter your ID to install it from the App Store or the first time you attempt to launch the app. This means the app cannot be updated (or reinstalled for free) unless the App Store is signed in to your account.To be clear, your copied app will continue to run on the second computer regardless of which account is active in the App Store — or even if you are not signed into any account.
