Here's how I'm keeping my 13" mid 2011 MBA for another few years

It's great that you have found a practical way to extend the useful life of your MBA. I sold my 2011 MBA to a close friend in 2013 and she still loves it. But I'm glad I sold it, and still very happy with my 2013 MBA. The slow USB 2.0 ports on the 2011 would be a deal killer for me today, I move around a lot of large files and get almost 400MB/sec with an external SSD or 180 MB/sec with a hard drive. You are limited to about 35MB/sec on the 2011 MBA (you could use thunderbolt for fast disks, but they are more expensive and there are fewer to choose from).

Same thing for 802.11ac wifi that is maybe 5 times faster than the wifi on the 2011 MBA, this is great for copying big files on my LAN. Then there are the limitations that the max memory available in 2011 was 4gb and 256gb was the biggest SSD. But arguably the biggest shortcoming is battery life. The newer models approach twice the battery run time because of more efficient chips.

These things all matter to me because of the way I use my computer, but I'm sure they wouldn't be much of an issue for others.

 

This is what I would suggest you:

- Get either Mavericks or El Capitan. Yosemite is full go bugs and El Cap is just the "optimized" version of it.
- Use uBlock origin, now available on both Safari (alpha) and Chrome
- For SSD, get the Transcend JetDrive, best bang for your buck.
- If you want AC Wifi and continuity (hands off) you can actually get it ordering a new card (I got it recently): https://github.com/dokterdok/Continuity-Activation-Tool/issues/41

weird, a 2011 MBA should not be considered "vintage" or "obsolete" yet...the 2009-2010 models just hit this status. usually it comes 6-7 years after last unit sold.

good points otherwise, except I disagree with the "don't upgrade" bit. Better to just wait a bit before upgrading until all the bugs are worked out

 

I bought my 2011 MBA (11") in August 2011 - 4GB ram, 256GB SSD. It's still running okay. I've never upgraded OS, still on Lion which is fine for what I need. Hoping now that it'll treat me well for another year or two at the least.

I still have my 2006 iMac running on Snow Leopard. This one's chugging a bit, mind you.

I too, was hoping for an upgrade with the recent MBPs, but felt underwhelmed by them and I really don't like the new keyboard. Practically no key travel.

 

Well done. Buy a quality product, take care of it, upgrade sensibly as needed, extract all life possible.

 

Your and my MBAs are identical twins. Mine was a refurb from Apple. Honestly, I still love it. I know the newer versions are nicer and better, but it does what I need it to do nicely and, like my 2012 MBP, I just really have no incentive to buy new and replace it. It's a light duty machine for me anyway (the MBA) but I absolutely love it.

 

Huge difference. https://github.com/el1t/uBlock-Safari

 

myself, i would try to trade up to a 2012. they are cheap these days and USB3 is a must for me because of huge backups (virtual machines).

cheers

scratch that i read MBP instead of MBA... duh

 

I would recommend upgrading to El Capitan. I had the lowest end late 2010 11” model, and El Capitan really sped it up and fixed a number of problems, compared to Yosemite.

 

Highly recommend El Capitan compared to the bug-fested Yosemite.
I have the 2012 (skipped 2011 for USB3), but wished I waited for 2013 Haswell version (for better battery life).
Oh well, other than the battery, it's still a great machine. Have done many things on it (from Office to Final Cut). Here's hoping for the battery to dip below 80% capacity so I can get it replaced.

 

Another UK-based mid 2011 MBA user here who was prepared to hand over dosh to Apple for a new MBA. New machines didn't happen so nowhere (reasonable) to go. All in all I am totally unimpressed with Apple. I used to recommend Windows users move over to Mac OS, I can't seriously do this any more.

My battery has gone through 1159 cycles and only holds half the charge. My keyboard is wearing with the 'a' and 'e' keytops worn off. I replaced the 256GB SSD with a 480GB third party device. I tried replacing the battery with one from Amazon but it wasn't a genuine Apple battery and I started having problems so I put the old one back in.

 

This is the Transcend JetDrive 480GB SSD which has performed faultlessly, and included a aluminium case so the previously installed 256GB SSD can be used as an external drive (for movies in my case): https://www.amazon.co.uk/gp/product/B00JKCHMLE/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

It seems the battery must have been eBay rather than Amazon. There's no "Designed by Apple". Appears to be a generic battery. Problems started after a few months. Can't remember exactly the details, but I reinstalled the old battery and the problems stopped.

 

I would only trust what ifixit.com recommends as far as third party batt. Surfing is fine mind you but this year, if I get that bike trainer I want and run that virtual reality training app, is gonna max out my 2011 and would probably forces me to upgrade

 

I also have MacBook Air '13 (2011), 4 GB, 256, i7. I haven't replaced the battery since it still holds 4-4.5 hours when I work (MS Office, iTunes, Safari). I use El Capitan and Mountain Lion. Will update to final version of Sierra later this year

 

I have just updated my 2010 MBA to El Capitan (as a lot of the apps I wanted to use required El Cap minimum)

Performance wise is fairly similar!
