Apple revealed the name change along with all of 10.12 Sierra's new features at WWDC. There's plenty to get excited about, but first you'd better check you're actually in line for the update. That's right - not every MacBook, iMac or Mac Pro will be getting upgraded on launch day. Here's a full list of Macs that are compatible to run the new macOS Sierra 10.12. If you have an iMac, MacBook, Mac Pro or Mac mini that is on this list, you are good to go with Sierra. By now, you'll no doubt already be aware about macOS Sierra. I have an old, not for me actually, MacBook Pro which I purchased at the end of 2010. I was expecting Apple won't drop the support of Mojave for MacBook Pro 2010 model, at least not for this time. But I was wrong. The latest Majove doesn't support it too. There is no need to worry. Even the oldest Windows 95 can be installed on Mac computer.

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Check compatibility
If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that it's too old to be opened on this version of macOS, or that your Mac doesn't have enough free storage space for the installation.
To confirm compatibility before downloading, check the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also find compatibility information on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.
Make a backup
Before installing, it's a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.
Download macOS
Insert key on macbook air. It takes time to download and install macOS, so make sure that you're plugged into AC power and have a reliable internet connection.
Safari uses these links to find the old installers in the App Store. After downloading from the App Store, the installer opens automatically.
- macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
- macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
- macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
Safari downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.

Install macOS
Follow the onscreen instructions in the installer. It might be easiest to begin installation in the evening so that it can complete overnight, if needed.
If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.
Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs macOS and related firmware updates.

My apologies if this is covered elsewhere, but I've searched all over with no luck.
I have a MacBook Pro that appears to be from 2009 (I'm still scratching my head over how to determine these things when a Mac won't boot). Anyway, the internal hard drive still boots up, but it's clearly defective. It does boot consistently, however, and I'm wanting to replace it.
I've tried installing both a 7200rpm mechanical disk and a 240GB SSD, but when attempting to install Mac OS X from DVD, it eventually just flashes that circle with a slash above the pinwheel of doom indefinitely. Strangely enough, I've tried this with another identical drive that has a Windows installation on it, and not only does it recognize the Windows install, but even begins to boot it up (before the invariable blue screen).
This occurs when holding C to force boot from a disc and also holding Option to choose the boot menu. If a blank disk, there's nothing (should be that way); if the HDD with the Windows install, it says Windows.
I've tried this with Snow Leopard and Leopard.
I've tried this with the internal optical drive and an external (both Firewire and USB to play it safe).
I'm pretty sure that Internet Recovery is not an option on this model as it goes nowhere.
Memory and all other hardware diagnostics via PC-Check are good.
I've made sure the cable is solid to the system board (again, the old drive boots, as does a drive with a Windows installation on it).
I've got to run for now, but I'm exhausting my resources here and need a solution pretty quickly. I'm sure I forgot to mention a few other things I've tried, but I gotta run.
Thanks all!
Ben
