As I’ve spotlighted over the previous month, one of the simplest ways to dramatically velocity up an older Mac is to replace its old hard drive with a new solid state drive (SSD). The method is super-easy on MacBooks and Mac Pros, surprisingly manageable on iMacs, and challenging on Mac minis, yielding 3X to 5X velocity boosts. However there’s another choice that may velocity issues up with comparatively little effort or experience: upgrading your Mac’s RAM.
RAM upgrades are straightforward and low cost. You’ll be able to anticipate to pay $90 or much less for sufficient (Mac-safe) RAM to run OS X Yosemite with out hiccups, or $180 for sufficient RAM to ensure you received’t want extra for years. Putting in RAM typically doesn’t void your Mac’s guarantee, and aside from a number of fashions, the one device you’ll want is a small screwdriver. Beneath, I’ll stroll you thru your greatest choices.
What Is RAM?
With out getting too technical, RAM (random entry reminiscence) usually refers to a small replaceable circuit board filled with reminiscence chips, designed to provide your laptop a high-speed non permanent work area — the place the place apps and information are saved whilst you’re actively utilizing them. Extra RAM lets your laptop run larger apps and extra apps on the similar time, lowering or eliminating the necessity to repeatedly load information out of your onerous disk or SSD.
Most present Macs ship with 4 or 8 gigabytes (GB) of RAM. A number of years in the past, there have been extra 4GB Macs on the market, however right this moment, should you don’t have at the very least 8GB of RAM and are operating OS X Yosemite, you in all probability would profit from extra RAM. I personally have 8GB in my Retina MacBook Professional and 12GB in my iMac; neither has apparent RAM-related points. Against this, 4GB Macs are very restricted in operating a number of apps without delay, whereas 16GB machines aren’t a lot totally different from 8GB or 12GB Macs besides when operating professional-quality (typically video modifying) apps. In case your Mac can run Yosemite, it may in all probability be upgraded to at the very least 8GB of RAM, if no more.
Apple usually makes Mac RAM swaps so simple as utilizing a small screwdriver to open a panel, the place you push down on clips to launch the RAM boards, then pop the brand new RAM into place. Most Macs have two RAM slots, every arriving stuffed, such {that a} 4GB Mac could have two 2GB RAM boards inside, and an 8GB Mac could have two 4GB RAM boards inside. Many iMacs and all Mac Execs have 4 slots. Whereas the iMac makes use of high-quality however consumer-grade RAM, the Mac Professional usually makes use of a few of the most costly RAM out there, and the bottom mannequin at the moment ships with 12GB of RAM put in.

How Can You Be Sensible About Swapping RAM?
I’ve upgraded the RAM in quite a few computer systems through the years, and realized a tough lesson within the course of: don’t beneath any circumstances try and low cost out once you’re placing new RAM right into a Mac. Let me repeat that: no matter you do, don’t reduce corners on RAM. Home windows PCs (and, not directly, their house owners) are typically considerably tolerant of imperfect RAM. System crashes, app crashes, failures in addition — these types of issues are frequent sufficient with PCs that it’s onerous to hint their causes. I’m not saying this to be snarky; dangerous RAM is just one of a bunch of components that may contribute to a PC’s instability.
However on Macs, I’ve discovered that these types of points very generally come right down to dangerous RAM, extra particularly, low cost RAM that labored fantastic when it was bought however began exhibiting issues after a system replace. You may save $10 or $20 on RAM that appears trouble-free with OS X Yosemite, however has points with the following OS X launch. I’ve personally seen this occur, and within the means of attempting to determine what went flawed, I’ve learn a whole lot (if not 1000’s) of equivalent person complaints on Apple’s Help Dialogue Boards. Low cost RAM is a much more frequent failure level for Macs than individuals understand.
You’ll be able to substitute the RAM boards individually, nevertheless it’s typically smart to swap pairs of two on the similar time to keep away from any refined specification variations between the outdated and new RAM. Traditionally, it was thought-about most secure — although not obligatory, and I don’t at all times comply with it — to have the identical quantity of RAM in every of two slots. (4-slot machines may have two individually matched pairs.)
Your greatest transfer is to purchase the appropriate RAM from a dependable vendor on day one. For this explicit sort of improve, I personally advocate Other World Computing’s OWC Memory selector page. It’s extremely visible, cleanly organized by Mac mannequin, and makes very clear what your particular machine’s RAM choices are — together with on-line set up movies to indicate you what must be executed.
I’ve additionally used Crucial RAM up to now, with combined outcomes — considered one of my “works right this moment, fails a yr later” RAM experiences was a Essential improve, however should you’re tech-savvy sufficient to type by means of complicated half numbers, Essential’s RAM will be good. Typically Essential’s costs are decrease than OWC’s, however OWC’s set up movies and the absence of post-purchase issues have tended to be well worth the small premium. I’ve been very pleased with the OWC elements I’ve bought for Mac upgrades, together with those featured in my iMac SSD update guide.
Mac-Particular RAM Steerage
So long as you comply with a single guideline — get at the very least 8GB of RAM to your Mac — just about any older Mac you need to improve might be higher off than it was earlier than. The kind and amount of RAM you’ll want will rely each on the Mac you’re utilizing and the stuff you personally do with it. Listed below are some Mac-specific pointers that might assist information your resolution.
MacBook/MacBook Professional. These two-slot machines are usually restricted to a most of 16GB of RAM, although older fashions are capped at 8GB. Use this OWC page to find the right RAM for your specific MacBook or MacBook Pro model, and go together with a 4GB + 4GB (complete 8GB) package except you’re in considered one of two conditions: in case your MacBook/Professional nonetheless has a non-SSD onerous drive which you don’t plan to exchange, otherwise you do video modifying in your laptop computer. In these conditions, think about 12GB (4GB+8GB) or 16GB (8GB+8GB) kits as an alternative. (Word that the Retina MacBook Professional doesn’t have user-replaceable RAM.)
MacBook Air. Just like the Retina MacBook Professional, you possibly can’t improve the RAM instantly within the MacBook Air, and strictly talking, you’re out of luck for RAM growth except you’re prepared to have the principle logic board up to date. However you possibly can simply add extra storage, both by means of an SSD upgrade (quicker, costlier) or the 13″ Air’s SD card slot (cheaper however slower). That slot is able to holding a 64GB or 128GB flash growth card that sits virtually flush with the laptop computer’s edge. Transcend’s JetDrive Lite (64GB/$37, 128GB/$74) is a highly-regarded option with a 4.5/5-star Amazon rating; and The MiniDrive lets you self-supply a Micro SD card of your chosen capacity for $20. These tiny drives additionally work within the 13″ and 15″ Retina MacBook Execs.
iMac. Each iMac launched since 2009 will be up to date to at the very least 16GB of RAM, and fairly just a few fashions (largely however not solely 27″ iMacs) can deal with as much as 32GB of RAM in 4 reminiscence slots. OWC’s iMac memory page will take you to the correct RAM for your machine. I personally have 12GB of RAM in my 2011 27″ iMac and really feel that it’s the appropriate minimal quantity of RAM for my every day skilled use, however should you’re not planning on doing video modifying or operating a whole lot of apps on the similar time, 8GB is okay. Equally, in case your iMac is getting used closely for skilled, time-sensitive duties resembling creating movies, music, or advanced paperwork, think about a bump as much as 16GB of RAM, presumably extra.
Mac mini. Blended information right here: beginning with the 2014 Mac mini, Apple stopped together with user-replaceable RAM on this machine, in order that’s not an possibility. However Mac minis offered from 2010 to 2013 will be upgraded to 16GB, and 2009 fashions are capped at 8GB. This OWC page will guide you to the right RAM for each Mac mini; my common recommendation is to stay to 8GB except you’re actually leaning in your mini as a workhorse for skilled apps or quite a few apps without delay. That’s not the frequent utilization state of affairs for a mini, so a modest improve might be fantastic.
Mac Professional. This beast of an expert laptop has the power to make use of as much as 128GB of RAM — Apple notably says 64GB (utilizing 4 16GB RAM boards), and ships with a minimal of 12GB (three 4GB RAM boards) put in. OWC’s Memory page spotlights all of the available Mac Pro RAM options, explaining in small print that you’ll want OS X Mavericks or newer to utilize over 96GB of RAM. As a common assertion, should you’re utilizing a Mac Professional, you in all probability want at the very least 12GB for no matter skilled functions you’re utilizing, and 16GB or extra definitely received’t damage.
Extra Data
In the event you’re searching for extra (and far quicker) storage quite than extra RAM, try my guides to replacing Mac hard drives with solid state drives, beginning with iMacs, persevering with with Mac minis, Mac Pros, and regular MacBooks, then ending with MacBook Airs and Retina MacBook Pros. The set up of SSDs requires slightly extra work and precision than swapping RAM, however you’ll discover even larger efficiency jumps, notably should you’re prepared to purchase the most recent and biggest SSDs really useful inside.
