Can ICloud See Apps I Download If I Use a Different Apple ID for TheApp Store

The logins are totally seperate. You can use one login for the app store and another for iCloud. There's no problems in that - iCloud would not suddenly require the password for the App Store login or anything like that

1. Three computers one Apple ID

If you delete a photo from iCloud Photo Library, it prompts you whether you are OK with the picture being deleted from all of your devices.The best way is to each person to have their own Apple ID. If all the three macs are your personal machines, disconnect two of them from iCloud Photo Library and switch on Photo Stream, that way the two machines will get the new photos and you can delete the ones you do not need.

2. Using macOS without an Apple ID?

No you do not need one at all. I do not get what with those recommendations. Thats about it.

3. Cannot change region of Apple ID without credit card details

This Apple support article explains that a valid payment method is always required when changing regions.You may be able to set up a new Apple ID for a different region without entering credit card information, but any apps purchased (whether free or not) with that Apple ID would require that Apple ID be signed in to get updates.To create a new account without a payment method, go to the App Store, iBooks Store or iTunes Store on your device. Tap Get on any free item and follow the steps for setting up a new account. When prompted for a payment method, None should be on the list. If it's not, you must enter a payment method.

4. Limit the use of my Apple ID on my kid's iPod Touch

You can assign your Apple ID to the App Store to share purchases and music but create a new ID to be used for iMessage, device backup, etc. on the second device. Apple Knowledgebase: Using your Apple ID for Apple services

5. Parallels Desktop - 1 Apple ID, 2 Macs

You will need two product keys, applications are not tied to your Apple ID unless you've bought them through the Mac App store, and most applications ship with the general terms of license that it's one key per person/per machine. Not used Parallels for a very long time so not sure if they've changed it but it used to be one key per machine

6. How to download past purchases from old Apple ID without waiting 90 days to switch back to new Apple ID?

I had the same issue due to the family now using a single itunes match account, with each of us having our own previous Apple IDs with downloaded music. I wiped one of the old computers not realising it was the only copy of my daughter's downloaded music. So a solution:Install/open itunes on a spare machine anywhere that does not need it routinely - pc/mac - login with the Apple ID you wish to download the music for, then download all the previous purchases. Copy the downloaded files to a usb/shared drive/any other shared resource and drop them onto iTunes on the computer that has the iTunes match ID logged in. When you try to play them, you will need to authorise the computer to play the music. Sync to the cloud, which matches them with iTunes match. Delete the local copy in iTunes of the files then redownload them from the cloud, which associates them with the iTunes match ID. Simple! (well not quite, but yes is effective)

7. How much money do I unlock an iPhone 5S Apple ID?

I'm not at all sure what you're asking.Do you mean to ask how much it would cost? As in, "How much money do I [need to pay to] unlock..."?And what are you trying to do, break into an Apple ID, or unlock an iPhone 5s so it can be used on any carrier? Or unlock the phone itself without the passcode? Or maybe get around Activation Lock?I'll try to address each.Unlocking a carrier locked iPhoneThe Apple ID is not part of the hardware, so an iPhone 5s doesn't have its own Apple ID. This is partly where I'm confused. Unlocking a phone for use outside of its original carrier does not involve an Apple ID and is something that most phone carriers like, say, AT&T, will do for free. I'd be shocked if they did charge anything for it, unless you're somehow still stuck in an old-school contract.Most phones now are sold without a contract, and many times won't be locked anyway. An iPhone 5s would have been sold originally way more than 2 years ago either way, so that phone surely is either no longer carrier-locked, or can be unlocked for free.It gets better: GSM iPhones that are locked are usually still unlocked for CDMA carriers like Verizon or Sprint in the US, and furthermore, iPhones sold in the US are not locked for international carriers. So a phone bought in the US on AT&T that's locked to AT&T could be used straight away on Verizon by putting in an active Verizon SIM card, without unlocking anything...or any carrier in any other country that's compatible with that phone (see below). So you may not have to even unlock the phone, let alone pay money to do so.(Note: Keep in mind, each iPhone has a few different hardware models, each of which have different LTE chip sets, and sometimes very limited carrier compatibility. For example, some iPhone 5s models only work on Verizon and Sprint. Unlocking this model would be useless for a GSM carrier like T-Mobile or AT&T. For non-US carriers, usually one model is most compatible world-wide, and another model is much less compatible. Check into this before you commit.)Now, if you're going through a third-party unlocking service that has a charge for unlocking your phone, just...don't. The only way to unlock an iPhone is through Apple's servers, which is normally done via the original carrier...because the carrier is the one that instigates the lock in the first place. Don't let a skeevy tech shop talk you into paying anything for, essentially, some kind of nefarious hack.Then there's the Apple ID, Activation Lock, or iPhone-breaking-into possibilities. Paying money to somehow break into an Apple ID, or an iPhone itself, is, at the very least, way against Apple's policy, and at worst immoral and maybe illegal, and not a thing I'd ever recommend.If you're in a bind with your own Apple ID and you forget the password or something like that, you can call AppleCare for free and have them try to verify your identity in various ways. If you're unable to, then for reals, you'll just have to swallow your frustration, create a new one, and move on in life. Apple takes personal security really, really seriously.If you're trying to wiggle around Activation Lock on a used iPhone you procured in totally non-nefarious ways, there's no way to do it without the original purchase receipt for the phone, or the password for the Apple ID that was originally signed into the phone before you got it. It's rare that Apple would allow you to do it without the original Apple ID password; there's a good reason Activation Lock is there, and it's that reason it's made to be so difficult to get around. If you do have either of those things, Apple can help you for free.If you're trying to get into a phone that's locked with a passcode, it's as simple as this: you can't, unless you remember the passcode. There is no workaround for it. There is no backdoor. There is no money to be paid.But your question, indeed, involves money: if you want to pay someone to do any of the above things, you may be able to find some 1337 h4x0r that can attempt to break into it somehow...but you're on your own on that one. I have no idea how much it would cost, nor do I want to know. This is hardly the forum to ask. Maybe try the deep web.I hope I got anywhere near answering your question. I assume you were asking about unlocking a carrier-locked phone, but it's worded very unclearly and I'd be beneficial if you'd edit it to clarify. How much money do I unlock an iPhone 5S Apple ID?
