In some Mac ranges, such as the MacBook Pro and iMac, you’ll have the choice of a model with integrated graphics or one with a separate, or discrete, GPU. My apps won't open on my mac. If you’re going to use your Mac primarily for playing power-hungry games, manipulating large images, or editing video or animation, you should choose a Mac with a separate GPU.

Buying a new Mac is exciting, but it can also be very confusing. For most of the Macs it sells, Apple offers a number of different configuration options, including different RAM capacities, storage sizes and disk types, and processors. For many people, it’s the last of those that’s most important. It’s arguable that processors, or CPUs, are now so powerful that they can do everything most of us need to do at a speed that is more than good enough and so choice of CPU isn’t important. But that’s not quite true, as we’ll explain below.
What is a processor?
Put simply, a processor is the ‘brain’ in your Mac. Until relatively recently the CPU was responsible only for taking input, executing instructions and passing on the results. Now, CPUs incorporate short-term memory of their own and, sometimes, graphics processors, or GPUs. In fact, when it comes to choosing a processor for your Mac, deciding whether to opt for one that has an on-chip graphics processor is one of the key decisions you’ll have to make. Macs that have processors with on-board GPUs tend to be less expensive than those that have separate graphics processors, but also are less capable when it comes to things like rendering 3D graphics and 4K video. To further complicate matters, new macOS features like Metal make excellent use of the hardware in GPUs, meaning the choice of graphics processor is almost as important as the choice of CPU.
What processor does my Mac have inside?
Since 2006 all Macs have used Intel processors — unlike iPhones and iPads which have Apple processors. Apple labels the Intel CPUs it uses in the Mac as Core i5 and Core i7 and differentiates them by speed in GHz. The other difference is the number of cores in the CPU and the number of CPUs in the Mac. So, roughly speaking a quad-core processor should be able to process instructions at twice the rate of a dual-core CPU. That’s not the case in the real world, as executing instructions relies on more than just the speed at which the CPU’s ‘brain’ can perform calculations (for example, it’s dependent on how quickly those instructions can be passed to and from the CPU). However, in an application optimized for multiple cores, you should notice a significant difference between CPUs with different numbers of cores.
Intel gives each generation of its processor a code name. Recent Intel CPUs have had names like Sandy Bridge, Haswell, and Skylake. Apple doesn’t use those names, or even talk publicly about which processor is in each Mac, but it’s known that the current crop of iMacs and MacBook Pros have Kaby Lake processors, which were the most recent available at the time they were released in 2017. So, if you bought it in the last year or so, your MacBook Pro processor is Kaby Lake. The slimline MacBook processor is known as Core M, designed specifically for low power mobile use. The MacBook Air and Mac mini have Haswell processors, as they were released in 2013. The Mac Pro uses a completely different family of Intel processors, designed for high-end workstations and known as Xeon. The Mac Pro, last updated in 2013, uses the Romley variant of Xeon.
What are the important features of a processor?
We’ve already talked about processors that have on-board graphics, such as Intel Iris and Iris Pro. These offer benefits such as taking up less space than discrete CPU and GPU chips and Mac’s that use them tend to be less expensive than those with separate CPU and GPU. However, they also tend to be less powerful.
The other key feature of a processor is the balance between speed and power consumption. CPUs that run faster use more energy and so generate more heat. This doesn’t just mean that fans have to run more often, it also uses more power — and if the Mac is a laptop, runs the batter down more quickly. Indeed, CPUs are often ‘throttled’ so that they don’t run at their theoretical maximum, in order to preserve battery life and reduce heat generation.
What about Turbo Boost?
Turbo Boost is a technology introduced by Intel and is designed to allow processors to run at speeds faster than those quoted on your Mac’s label in certain circumstances. Remember we said that CPUs are often throttled to prevent overheating? Turbo Boost monitors the power consumption and heat of the CPU and removes that throttle when it’s safe to do so. So, for example, a quad-core 2.8GHz Mac Pro could run as fast as 3.8GHz in the right circumstances.
Which processor should I choose?
It’s likely that if you’re buying a new Mac, you’re choice of processor will be made from the Core M, Core i5, and Core i7. Not all Mac models offer a choice of all three. The Core M, for example, is specifically designed to minimise power consumption in mobile devices and is used only in the MacBook. If you’re buying a MacBook Pro or iMac, you’ll have the choice of Core i5 or Core i7. Likewise, if you buy a MacBook Air or Mac mini, although those machines use older versions of Intel processors. And, as we said earlier, if you buy a Mac Pro, you’ll be able to choose from Xeon workstation processors with multiple cores.
There are two decisions you’re likely to have to make: i5 or i7 and dual-core or quad-core. Generally speaking, in terms of speed, a dual-core i5 is the slowest and a quad-core i7 the fastest. That, however, is not the whole story. In order to get the most from multiple cores, you’ll need to be performing tasks that really benefit from the ability to execute more instructions simultaneously. So, tasks like 3D rendering, video editing and working with large images in Photoshop will all improve noticeably with a quad-core vs a dual-core processor.
Core i7 processors have two main benefits over Core i5: larger cache and hyper-threading. The presence of a larger cache means the CPU can store more data locally and so spend less time transferring them back and forth to RAM. Hyper-threading allows the CPU to simulate additional cores. So, a quad-core i7 with hyperthreading behaves like and eight-core CPU.
The benefits of larger cache and hyperthreading are seen in scientific applications, where large calculations are performed and their results stored, as well as the 3D animation and 4K video editing.
Integrated vs discrete graphics
As we discussed earlier, some Intel processors have GPUs onboard. In some Mac ranges, such as the MacBook Pro and iMac, you’ll have the choice of a model with integrated graphics or one with a separate, or discrete, GPU. If you’re going to use your Mac primarily for playing power-hungry games, manipulating large images, or editing video or animation, you should choose a Mac with a separate GPU. On the other hand, if you’re mostly going to use it for writing, email, social media and editing your own photos, a CPU with integrated graphics, like Iris, is fine.
Can I upgrade the processor in my Mac?
That’s a flat no, sadly. There have in the past been Macs that had processors that could be upgraded, but now they’re soldered firmly in place and so your Apple CPU can’t be removed. That makes the choice you make when you buy your Mac even more important. The good news is that for most users every processor that ships with a currently available Mac, even those that haven’t been updated in several years, is absolutely fine and will run as fast as you need it to.
If I can’t upgrade the processor, how else can I speed up my Mac?
Two of the most effective ways to make your Mac go faster are to install more RAM and swap your hard drive for an SSD. Those both cost quite a bit of money, however. A much less expensive and much easier way is to get rid of the ‘junk’ files that can clog up your Mac. These are installed by applications, or by the system, or downloaded to your machine by websites. Deleting them one by one is a long and difficult process, but CleanMyMac X makes it very easy. CleanMyMac identifies files on your Mac that either serve no purpose, that you’re unlikely to need, or that are large and haven’t been opened for a while.
You can scan your Mac with one click and CleanMyMac will report back to you with the files it thinks you can delete and how much space it will save you — it can be tens of gigabytes. You can then review them and choose which to get rid of or press Delete and get rid of them all. CleanMyMac also makes it easy to uninstall apps you no longer use and removes all their associated files. You can download it free here.

I use rsync alot myself to copy files from and to work. Any projects Im currently working on for an extended period of time get their own folder and rsynced between work and home.
Though Im usually good about rsyncing before I leave work or home, I forget occassionally.
So I dont accidentally overwrite any changes - I usually use the -n flag. That does a 'dry run' of rsync showing possible changes without actually making them.

Some time ago I was looking for a tool to binary-compare two directories too. Diff is a bit of an overkill in this case since I was not interested in the details of differences between the two dir structures, I just wanted to know whether they're the same or not.

I've found only one GUI application that would satisfy my needs, it was Kdiff3. However there's a lot more simple and elegant solution. :-) Start a shell and enter the dir that you want to compare with another, then run a 'find':
![Best Diff App Mac Best Diff App Mac](/uploads/1/3/4/1/134134042/271084412.png)
cd /path/to/dir1
find . -type f -not -exec cmp {} /path/to/dir2/{} ';' -print
App for samsung. This will print the name of each file that differs between the two directories.
It seems to me that any items uniquely found in dir2 won't be reported by the find command.
make sure to format this command exactly the same and including these: ' ' when needed
find . -type f -not -exec cmp {} /path/to/dir2/{} ';' -print
I really just wanted to thank you and everyone in this thread. Relocating and cleaning up my mothers age old backup folder that is filled with duplicates has been made so much easier.
You have all my grattitudes.

Some people may haven't found the feature, yet, but Toast has a 'Compare' function hidden in the Utilities menu, it'll provide a nice colored output of the differences.
And TextWrangler also supports diffing of folders.

I prefer the use of Subversion to stay in sync with several computers with different OS-es.

I too am trying to keep a desktop and a laptop in sync - both running OSX. Of course the laptop has much less hd space which means I need to be selective. I have been using Unison very successfully so far for documents in general and for certain application preferences. It is very fast and a pleasure to use.
The complications come in due to the fact that applications do not always play nice with copying preferences and the like. For some apps, I haven't figured out which pref and support files are safe to copy. For example, taking a simple-minded approach to syncing causes MS Office to sort of re-install itself each time. Firefox preference copying is also not obvious to me.
Is anyone else sync'ing app preferences and executables?
Also, I am curious how people are using Subversion.

This hint makes me realise I'm not alone in thinking there must be simpler solution to the problem of keeping a directory in sync between work and home computers, without having to lug an external hard drive around. I need to keep a large (about 5GB) directory of pdf files in sync between a work PC and a home Mac, all sorted into appropriate sub-directories. I currently do this manually by copying any changed files onto a flash memory stick and then copying them onto the other machine when I get home. The flash drive is not big enough to contain a copy of the entire directory, but can easily hold just the changed files. Ideally, some little program or script would identify added or changed files, copy them to the flash drive, then put them into the corresponding sub-directory when the flash drive was connected to the other machine. Then it would repeat the process in the opposite direction.
Synchronization utilities are no good as they require a disk big enough to hold the entire directory. Unison is no good as it requires a network connection between the 2 machines (which most admins baulk at).
Anyone have any other ideas?

I have a question about this hint.. I'm not too well versed in terminal, but I'd love to do this with my two music folders (one on my external HD,and one on my internal). Do I put all of that code into terminal (including the '|'s) in one line, or do I run them as three separate commands in succession?
Also, where does this diffs.txt show up?
Thanks!

Put it all on one line. The diff.txt file will show up in your working directory. If you just started terminal and did not change directories, this will be your home directory (i.e., not the Desktop or Document directories).
One tip: to quickly enter the two folders you want compare, first type the diff -rq command. Then drag-and-drop the first folder onto the terminal. The path will automatically appear. Then drag-and-drop the second folder. Then type the rest of the command.

Users trying to sync home directories between two computers (say a laptop and a desktop) may find Apple's Portable Home Directory feature of Mac OS X Server helpful. I haven't used it, so I can't say how well it works.
