Mac Os Mojave Patch Tool For Unsupported Macs
MacOS Mojave Patcher (formerly macOS High Sierra Patcher and macOS Sierra Patcher) is a small yet powerful tool that can help you create a bootable USB drive that can be used to install macOS Mojave on Mac computers older than late 2009, basically acting as a macOS Mojave patch for unsupported Macs. Speaking about macOS Mojave Patcher, it is a software tool that allows you to run the latest macOS Mojave on your unsupported Mac. Credits for developing this application goes to a developer who goes by the name Dosdude. If selected in the macOS Post Install tool, your Mojave install will have a program named 'Patch Updater' located in your /Applications/Utilities folder. This program will alert you when new updates to patches are available for your machine, and will prompt you to install them.
Does the Mac App Store check for macOS 10.12 hardware compatibility before downloading?
According to what I've been reading on the web, my MacBookPro 5,5 (mid 2009) should not support macOS 10.12, Sierra. However the Mac App Store allows downloading it.
I would like to prevent downloading 5GB of files and finally discover that the installer says 'your mac is not supported'.

Officially your MacBook Pro (13' Mid-2009) is not supported by macOS Sierra. However, for whatever reason, the option to upgrade to macOS Sierra is appearing in the App Store for a whole range of unsupported Macs. In fact, today I saw this occur on a MacBook Pro (15' Late-2008) model that was running Snow Leopard 10.6.8, even though Apple doesn't officially support upgrading from this hardware or OS.
As to whether you can install it, the answer is yes, even though this isn't officially supported by Apple. If the App Store allows you to download the upgrade, then you could just download it (without installing it) and then make a copy of the installer. Once you've got a copy you could try installing from the original downloaded location to see what happens. If this doesn't work you can download the macOS Sierra Patcher Tool for Unsupported Macs. Make sure you read all the information on this page as it contains important information you should weigh up before proceeding. If it was me I would not proceed without a full backup ready so you could recover your system if all goes bad.
In the end, whether you should download the upgrade is up to you. Do you want macOS Sierra? Many of its new features are not supported even on Macs that are officially supported by the upgrade - so the answer to this will depend on what appeals to you in upgrading to macOS Sierra? To help you decide, go to Upgrade to macOS Sierra and scroll down to the Feature Requirements section.
If what appeals to you isn't likely to work because it's only supported on much newer Mac models, then I wouldn't bother.

following an explanation from the website www.trustedreviews.com
Despite Apple's guidance that it's only late-2009 devices and onwards that will be able to run the OS, theoretically you should be able to run Sierra on computers with a CPU utilising the Penryn microarchitecture.

Of course, just because it's possible doesn't mean it's straightforward, which is why developer Colin Mistr (aka dosdude1) created the macOS Sierra Patch Tool.That utility, along with a USB drive with a capacity of at least 8GB and a copy of Sierra, should let you install macOS on that handful of older devices.
All the usual caveats apply: installing macOS Sierra on an unsupported computer could bork it (and your data), as well as likely voiding your warranty.
On certain devices, too, the workaround will kill your Wi-Fi functionality. These are the late-2008 and mid-2009 MacBook Air, early-2008 and mid-2008 MacBook Pro, early-2008 iMac and early-2008 Mac Pro.
In other words, you should have bit of technical know-how if you're going to try this, and backup all your data first. While we know this worked on Sierra dev previews, we're also unsure if Apple has managed to patch the borderline 'hack', so let us know your mileage in the comments below.
If you do want to give it a go, though, you can find step-by-step instructions and download the macOS Sierra Patch tool here
