Is my 2009 MacBook out of date?

If it is working condition, you can use it.

It is definitely out of date. That appears to be a MacBook (13-inch, Late 2009) with a white plastic case which can't run anything later than High Sierra.

High Sierra is six major versions behind Sonoma . Adobe, Microsoft, and the like stopped offering any applications for High Sierra ago, and even other application vendors known for supporting old versions of the OS for a long time have largely moved on.

On the flip side, that laptop will run some old 32-bit games that vendors never updated to work with Catalina (which dropped support for 32-bit applications) and later.

...and it’s not quite working right.

Can you provide details of what seems wrong?

Let's make sure what Mac you have. Many users shorten "Macbook Pro" to just "MacBook," but those are two different Apple models. You can find which you have by doing "About this Mac..." from your Apple menu:

No 2009 Macbook Pro can run higher than macOS 10.11 El Capitan.

As Servant of Cats points out, a MacBook (not a "Pro") that is Late 2009 can run up to macOS 10.13 "High Sierra." If an Early or Mid 2009, 10.11 El Capitan is the highest OS possible

What’s wrong with it? Errors? Issues?

MacBookPro5,3 is MacBook Pro (15-inch, Mid 2009).

That Mac is supported as far as OS X 10.11, which is from 2015, which last got a patch in 2018.

If it works, sure, use it. If it doesn’t work, it’s probably not worth repairing. Not past swapping a failed HDD or failed memory, which are both user-serviceable on that Mac. If the HDD is failing, an SSD would speed it.

Model ID "MacBookPro5,3" corresponds to a MacBook Pro (15-inch, Mid 2009). Sometimes Apple reuses an ID for many different Macs, but this time, there was only one match.

You can only upgrade that Mac as far as OS X 10.11.6 (El Capitan).

As the second report shows, that Mac has an Intel Core 2 Duo CPU with only 2 cores, and has only 4 GB of RAM. The machine can take 8 GB of RAM. It might have a SATA SSD installed, but most of those MacBook Pros would have shipped with 320 GB or 500 GB mechanical hard drives.

The OP will probably need to use a modern Mac or PC to download the El Capitan .DMG installer onto a USB flash drive, for transfer to the 2009 MacBook Pro. The MBP needs to be running some version of Mac OS X to open the .DMG and run the installer, but Snow Leopard may not be able to access modern https pages like the pages which contain this thread, or the page holding that Support article.

True. But the link there (shown below) is http, not https. So no TLS issues with the direct download path.

As I said in my post above, your computer is obsolete/vintage. Modern websites have moved on and apps have abandoned old technology. I would not spend any money, time, or effort on such an old computer.

Your computer is obsolete/vintage. It can not run current/future apps and it can not get security updates.

Linux or one of the BSDs will probably load on this Mac, but that’ll be a rather different experience from macOS.

I jumped the gun on that. Did a search for "A2009" in MacTracker, didn't find anything, so did another search with "2009" (without thinking), which of course matched lots of products in jumbled-up order.

Mr. Jones is correct. We need more information on exactly which 2009 Mac notebook you have. The "a2009" is not particularly helpful in determining this.
