Jeg ville minimum sætte 16GB i, f.x.:

Svjv. har Mactracker altid check på, hvor meget RAM, der duer. De skriver
32GB for iMac 2011.
Efter råd fra bl.a. Jens Kristian Søgaard er jeg HOLDT HELT OP med:
- at bruge "renseprogrammer" som CleanMyMac, MacKeeper, Memory Clean,
o.lign
- at reparere disktilladelser
- at defragmentere
Dét virker og gør livet lettere :-)
Læs her en række råd om, hvad der er fornuftigt...der mangler lige en
bemærkning om, at man skal afprøve sin backup løsning, så man VED, den
virker. Altså at ens backup er intakt og at den i praksis kan bruges, hvis
ens Mac forsvinder sporløst/brænder/dør:

Re: Best clean up utility for Mac OS X?
in response to Iamawesome997
How to maintain a Mac
1. Make redundant backups, keeping at least one off site at all times. One
backup is not enough. Don¹t back up your backups; make them independent of
each other. Don¹t rely completely on any single backup method, such as Time
Machine. If you get an indication that a backup has failed, don't ignore it.
2. Keep your software up to date. In the Software Update preference pane,
you can configure automatic notifications of updates to OS X and other Mac
App Store products. Some third-party applications from other sources have a
similar feature, if you don¹t mind letting them phone home. Otherwise you
have to check yourself on a regular basis. This is especially important for
complex software that modifies the operating system, such as device drivers.
Before installing any Apple update, you must check that all such
modifications that you use are compatible.
3. Don't install crapware, such as ³themes,² "haxies," ³add-ons,²
³toolbars,² ³enhancers," ³optimizers,² ³accelerators,² ³extenders,²
³cleaners,² "doctors," "tune-ups," ³defragmenters,² ³firewalls,² "barriers,"
³guardians,² ³defenders,² ³protectors,² most ³plugins,² commercial "virus
scanners,² "disk tools," or "utilities." With very few exceptions, this
stuff is useless, or worse than useless.
The more actively promoted the product, the more likely it is to be garbage.
The most extreme example is the ³MacKeeper² scam.
As a rule, the only software you should install is that which directly
enables you to do the things you use a computer for ‹ such as creating,
communicating, and playing ‹ and does not modify the way other software
works. Use your computer; don't fuss with it.
Never install any third-party software unless you know how to uninstall it.
Otherwise you may create problems that are very hard to solve.
The free anti-malware application ClamXav is not crap, and although it¹s not
routinely needed, it may be useful in some environments, such as a mixed
Mac-Windows enterprise network.
4. Beware of trojans. A trojan is malicious software (³malware²) that the
user is duped into installing voluntarily. Such attacks were rare on the Mac
platform until sometime in 2011, but are now increasingly common, and
increasingly dangerous.
There is some built-in protection against downloading malware, but you can¹t
rely on it ‹ the attackers are always at least one day ahead of the defense.
You can¹t rely on third-party protection either. What you can rely on is
common-sense awareness ‹ not paranoia, which only makes you more vulnerable.
Never install software from an untrustworthy or unknown source. If in doubt,
do some research. Any website that prompts you to install a ³codec² or
³plugin² that comes from the same site, or an unknown site, is
untrustworthy. Software with a corporate brand, such as Adobe Flash Player,
must be acquired directly from the developer. No intermediary is acceptable,
and don¹t trust links unless you know how to parse them. Any file that is
automatically downloaded from a web page without your having requested it
should go straight into the Trash. A website that claims you have a ³virus,²
or that anything else is wrong with your computer, is rogue.
In OS X 10.7.5 or later, downloaded applications and Installer packages that
have not been digitally signed by a developer registered with Apple are
blocked from loading by default. The block can be overridden, but think
carefully before you do so.
Because of recurring security issues in Java, it¹s best to disable it in
your web browsers, if it¹s installed. Few websites have Java content
nowadays, so you won¹t be missing much. This action is mandatory if you¹re
running any version of OS X older than 10.6.8 with the latest Java update.
Note: Java has nothing to do with JavaScript, despite the similar names.
Don't install Java unless you're sure you need it. Most users don't.
5. Don't fill up your boot volume. A common mistake is adding more and more
large files to your home folder until you start to get warnings that you're
out of space, which may be followed in short order by a boot failure. This
is more prone to happen on the newer Macs that come with an internal SSD
instead of the traditional hard drive. The drive can be very nearly full
before you become aware of the problem. While it's not true that you should
or must keep any particular percentage of space free, you should monitor
your storage consumption and make sure you're not in immediate danger of
using it up. According to Apple documentation, you need at least 9 GB of
free space on the startup volume for normal operation.
If storage space is running low, use a tool such as the free application
OmniDiskSweeper to explore your volume and find out what's taking up the
most space. Move rarely-used large files to secondary storage.
6. Relax, don¹t do it. Besides the above, no routine maintenance is
necessary or beneficial for the vast majority of users; specifically not
³cleaning caches,² ³zapping the PRAM,² "resetting the SMC," ³rebuilding the
directory,² "defragmenting the drive," ³running periodic scripts,² ³dumping
logs,² "deleting temp files," ³scanning for viruses,² "purging memory,"
"checking for bad blocks," or ³repairing permissions.² Such measures are
either completely pointless or are useful only for solving problems, not for
prevention.
The very height of futility is running an expensive third-party application
called ³Disk Warrior² when nothing is wrong, or even when something is wrong
and you have backups, which you must have. Disk Warrior is a data-salvage
tool, not a maintenance tool, and you will never need it if your backups are
adequate. Don¹t waste money on it or anything like it."
