• An in-depth look into Mac OS X and iOS kernels. Powering Macs, iPhones, iPads and more, OS X and iOS are becoming ubiquitous. When it comes to documentation, however, much of them are shrouded in mystery. Cocoa and Carbon, the application frameworks, are neatly described, but system programmers find the rest lacking.
• An ISO file is a file that contains the complete image of a disc. Particularly ISO files are frequently used to transfer or share CD/DVD files. Mostly used as operating system installation files container that holds the files like Windows 10 ISO or other ISO. It can also be used to back up your files and transfer it.
• Apple's mobile operating system, iOS, has been considered a variant of macOS. A prominent part of macOS's original brand identity was the use of Roman numeral X, pronounced 'ten' as in Mac OS X and also the iPhone X. Apple began naming its releases after big cats, which lasted until OS X 10.8 Mountain Lion.

If there’s a single disappointment in the release of Apple’s first wave of M1 Macs, it’s the lackluster launch of iOS apps running inside of macOS. What should be an amazing unification of Apple’s platforms and a massive expansion of the Mac software base is, instead… kind of a non-event.

MacOS Sierra (version 10.12) is the thirteenth major release of macOS (previously known as OS X and Mac OS X), Apple Inc.' S desktop and server operating system for Macintosh computers. The name 'macOS' stems from the intention to uniform the operating system's name with that of iOS, watchOS and tvOS. Sierra is named after the Sierra Nevada mountain range in California and Nevada.

Running iOS apps on the Mac can be a little weird, it’s true. But it can sometimes be good. Unfortunately, a lot of interesting iOS apps just aren’t available at all, because their developers have removed them from the Mac side of the iOS App Store.

It’s not a great situation. It needs to get better. Here are some ways that might happen.

What developers can do

Though iOS app developers with the Apple silicon Developer Transition Kit could build their iOS apps for Mac and run them to get an idea how they’d perform on macOS, I understand that many developers didn’t do this, and others didn’t feel comfortable letting their iOS apps out into the wild without first giving them a try on a real M1 Mac. A lot of them opted to just stay on the safe side and opt their apps out.

But I hope it’s a temporary situation. While iPad and iPhone apps have some quirks in a Mac context, they honestly work better than I expected. And I think users are probably more forgiving of quirks than perhaps developers are. I hope that perfect won’t be the enemy of good, and that users won’t be deprived of apps they love from iOS just because they’re not quite up to a developer’s very high standards.

What I’m hoping is that developers will look at how their iOS apps perform on the Mac and decide that they do want them there—and will be driven to improve them. Improving support for iPad features like cursors and keyboard shortcuts will make an app better on the Mac, too. And developers can go even further by embracing Catalyst, which lets those iOS apps run as full Mac apps, with a more normal menu bar and other Mac adaptations. (Apps running with Catalyst will also run on the installed base of Intel Macs, which will be a majority of Macs in operation for a few years yet.)

Finally, I’d encourage app developers to listen to their customers and understand that an iOS app might be a better option than the alternative. I’m so sick of being kicked to lousy web-based experiences on the Mac when there are excellent apps for those services on iOS. Even a slightly strange iOS experience, running in a standalone app, beats out keeping it in a Safari tab that I’ll invariably close by accident.

What Apple can do

This isn’t all on developers. If Apple wants to benefit from having iOS apps run on all future Mac hardware, it’s going to need to keep pushing.

Part of that push will need to come on the software side. Apple needs to continue to develop Catalyst and make it as easy as possible for iOS developers to make apps that work great both on iPads with the Magic Keyboard attached, and on Macs. The less work developers have to do to make their apps great across a wide range of Apple devices, the more likely they are to do the work.

Apple needs to bring across more of its own technologies, too. The Shortcuts app is a key way to automate functions on iOS, but it doesn’t exist on the Mac, and many iOS apps will be a little less functional until it does.

But Apple’s biggest impact can come with the decisions it makes about hardware. The reason some iOS apps feel weird on the Mac is that they were designed for touch, not for a cursor and keyboard. Introducing Macs with touchscreens won’t change the Mac’s status as a mouse-first operating system, but it will offer alternate modes of input—and open up better compatibility with some iOS apps.

And imagine if Apple made a two-in-one convertible laptop, with a screen that could be wrapped around the back to make it temporarily more like an iPad. A lot of users would love a laptop that could transform into a tablet from time to time—but the apps need to be there.

What users can do

Developers have it rough. They’ve spent the summer wrestling with some major changes in macOS Big Sur, plus the transition to Apple silicon. They deserve your respect and your politeness.

That said, if there’s an iOS app that you love that’s not available on the Mac, it’s worth politely contacting that developer. Explain to them—politely!—why you want to run that app on the Mac, and why it’s a superior option to whatever their Mac solution is today. The more demand developers hear, the more likely they are to prioritize bringing their iOS app to the Mac.

Another thing to keep in mind: Every iOS developer is a Mac user, because the only way to develop apps for iOS is to use Xcode. This means that most iOS developers aren’t going to look down on Mac users who want their favorite iOS apps to run on the Mac—because they probably do, too.

Finally, all of us need to be patient. It’s the very earliest days for Apple silicon on the Mac. I’ve talked to some developers who have been working on bringing their iOS apps to the Mac since the initial Mac Catalyst announcement in the summer of 2019—and they’re still not there. The first version of Catalyst was limited, and so many of them waited for the version in Big Sur. It takes time to do it right. I’m confident that more apps are on the way. But we all need a little patience.

Still, developers: If your app runs okay on the Mac and there’s no huge business reason to bar Mac users from using it, why not check that box? Chances are good that your customers will thank you for it.

Updating to iOS 14? This thread discusses a trick to enable iTunes syncing to work in El Capitan. Reinstall iTunes while the phone is connected:

Further details are here:

1. Make sure you are running 10.11.6 using the Combo to any version of 10.11 and Security Update 2018-004.
2. Upgrade to iTunes 12.8.2.3.
3. From TuringTest2 on another thread:

Assuming a suitable version of iTunes is in place then in Finder use the menu item Go > Go to Folder..., copy the following text, paste it into the dialog box and press enter:

/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/Current/Resources

Unlock your device and connect it to USB. Double click on MobileDeviceUpdater in the folder that has opened. It should notify you of a software update. Install it and iTunes should hopefully recognize your device.

On September 19, 2019, iOS 13 was released. Present requirements for iOS 13 include Mac OS 10.11.6 for iTunes 12.8 as a bare minimum.

Two factor authentication logins for AppleID unlocks was introduced on Mac OS 10.12.4. If your iOS is current for it, you can usually use it to unlock either from another current iOS device, or http://iforgot.apple.com if you don't have a Mac.

On May 29, 2019, it was found that iOS 12.1.5 could sync with iTunes on Mac OS X 10.10.5 if you kept iTunes 12.5.5.

This thread discusses more of the inconsistent requirements that were initially stated:

https://www.imobie.com/support/how-to-downgrade-from-ios-12-to-ios-11.htm offers a means of downgrading from iOS 12 to iOS 11, if no other means work to link an elderly Mac that can't be updated to 10.11. Be very careful to backup your data properly to avoid problems. Consider a lightning port data transfer device if you need to backup data. And remember no backup is complete, unless you know you have two working copies.

Downgrading Mac OS X is possible in many cases, but your iOS is not at all. Downgrading a Mac is described here:http://discussions.apple.com/docs/DOC-1948

iOS 12 & Yosemite -is a new tip I constructed to cover what can be done for those with Yosemite when downgrading the iOS is no longer possible.

For iOS earlier than 5, see this tip:Which OS do I have and where should I post?So be sure to look this over before upgrading your iOS and backup/sync your iOS with your Mac:

Mac OS X 10.5.8 (Leopard) supports PowerPC Macs, iTunes 10.6.3, iOS 5.1.1.

Mac OS X 10.6.8 (Snow Leopard) supports Intel only Macs, but does support PowerPC applications, iTunes 11.4 and iOS 6, and iOS 7.

Mac OS X 10.7.3 (Lion) supports iCloud except for iCloud Drive in its current iteration and the new Notes.

Mac OS X 10.7.5 (Lion) (link explains the pitfalls of losing PowerPC applications) supports iTunes 12.2.2.25 (available from Software update as of 10/24/2015), iOS 8 and iOS 9.0.

Mac OS X 10.8 (Mountain Lion) is required for iTunes 12.3 and iOS 9.2 and iOS 9.2.1(except iCloud Drive, and the new notes). Does not support iOS 10 or iTunes 12.5.1 according to the Wikipedia below.Mac OS X 10.9.5 (Mavericks)one user has said is required for iOS 10 and iTunes 12.5. It is though unable to sync with iOS 11.Mac OS X 10.10 (Yosemite) is required minimum for the new iCloud Drive and iOS 11 (except for Notes, which requires El Capitan). iTunes 12.7.0.166 is needed for iOS 11. Also note, anyone who can install Mountain Lion can also install El Capitan, which supports all iOSes up to the iOS 14.x as of (April 2, 2021). That's covered earlier in this tip.

Mac OS 10.12 (Sierra) currently has no special requirements as of April 2, 2021, however is a free path to upgrade from Macs that shipped with Lion, that upgraded to 10.7.5 or later, and then updated to Sierra to be able to synchronize with iOS 12.

iOS 12 was released September 17, 2018. Please make sure to backup your data on your iphone, ipad, or ipod touch and not apply any update until you are certain that iTunes on your Mac or PC can handle it.

Stuck in Mavericks, Mac OS X 10.9.5? There is a published way to downgrade your iOS.

Note: this is not for the faint at heart, but sure is better than having to upgrade your Mac OS X prematurely for an App you can't afford upgrading on your Mac. Consider your reason for being stuck. If it is a software that won't run on 10.11.6, ask on the forum for other software titles that are comparable, since you can upgrade to Mac OS X 10.11.6 to get the current iOS of April 2, 2021.
