2.4GHz vs 2.7GHz MacBook Pro Retina?

What is the performance difference? The 2.4 only comes with 256GB of flash memory and the 2.7 doubles it and the RAM too. It's about £420 difference. I was thinking if I get the 2.4 I could buy an external SSD if I run out which I'm sure I will..

The difference is speed. The 2.7 runs at a higher clockspeed and is therefor faster. The processor is not upgradable though,so you have to choose wisley when you purchase your Mac.

2.4GHz vs. 2.7GHz MacBook Pro Retina, 2.4GHz vs. 2.7GHz MacBook Pro Retina

I'm looking at getting a 15inch retina display MacBook Pro with 16GB of RAM and a 512GB SSD. When configuring the laptop online I noticed the price difference between the 2.4GHz processor and the 2.7GHz processor is only $100. Both are quad core i7 processors. The computer will be used for photo and video editing. I also plan on keeping the computer for 4-5years. Is it worth the $100? Thanks.

if you can spare the extra $100 sure I would get the 2.7 since the processor can't be upgraded after purchase.

4GB memory on new MacBook Pro Retina 13 with 2.4GHz dual core i5 processor &128GB flash storage

Hello,
I'm completely new to the mac world but I'm fed up with pc's and all the insanity with processor problems, viruses, etc. I'm seriously looking at replacing my HP laptop with the new MacBook Pro Retina 13 with 2.4GHz dual core i5 processor, 4GB memory (RAM) & 128GB flash storage, OS X Mavericks (not sure which version). My concern is whether this will be reliably & consistantly fast & smooth both in desktop apps & internet use. I don't need it to do somersaults or anything too advanced. I would mostly be using Pages & spreadsheet apps & internet. It would double as my daughter's computer for cyber school so it's crucial that it runs quickly & efficiently. If she can't complete everything on time or log in to her online sessions because of a computer issue we'll be up a creek without a paddle since this particular cyber school's tech department is still working off of pc's running Windows XP. My father, thus far a pc user, thought I should consider moving up to 8GB memory but I was hoping that with flash storage being faster, I would be able to avoid the extra $100 for the upgrade to 8GB. My biggest fear is finding myself as frustrated & angry as I am now with all of my pc's, ready to take a sledge hammer to them because they take forever to boot, launch apps, internet or do just about anything (that is if they're even fuctioning at all- not joking). Does anyone have any advice or input? Thanks!!
P.s. On Apple's site I found a refurbished late 2013 model of the MacBook Pro Retina 13 with all of the same specs as listed above (4GB, not 8GB), running OS X (doesn't say which one) but for a bit less than a brand new one. Is this the same model as what they're currently selling new in their store or did they just upgrade everything to match what is being offered in the current "new" model? I realize this may be a dumb question but I can't seem to find anything online indicated that Apple has released a model newer than what was released late last year (October 2013, I believe), except that the model released then came with SSD storage instead of flash.

No computer is fault free but Apple MBPs have a good track record. In those cases where problems do arise, Apple has the best support in the industry.
A MBP with 4 GB RAM with the SSD storage should be adequate for your needs.

The latest MBP models came out in October 2013, so it will be the same, with the same warranty and telephone support. The difference will be that the price will be less and it will be delivered in a plain white box.
I have purchased three MBPs from the refurbished section. I have never been able to detect any cosmetic differences and will go that route again.
Ciao.

Need help deciding on which Mac to get? Macbook Air vs Macbook Pro Retina

Hey im new here, sorry if these questions get repetitive but im investing a lot of money and dont have much knowledge on computers so i came here. So my options are :

8GB 1600MHz LPDDR3 SDRAM
128GB PCIe-based flash storage
$1249.00
Option 2

$1299.00
here is how i find myself as a computer user...
i use a computer everyday as a college student... a lot of microsoft programs and internet usage...
occasionally i use netflix but i find myself hooking it up to a tv if i watch or stream off my comp
here is my issue why do i need a retina if i can watch most things on tv now that they have internet integrated such as netflix youtube.
so what would be more useful more hard drive space with 8gb of ram or less harddrive space with faster processor
thank you in advance as this is my first post

I had the same question as I was starting grad school and my old MacBook Pro was just getting too tired and slow.
I visited the Apple store and spoke with four different employees and they each came to the same conclusion- separately- that the Pro was the way to go.
If you upgrade your flash like you mentioned you might want to do with the Air that's great, but with the pro upgrading your flash automatically upgrades your RAM as well, doubling you from 4 to 8. I kept going back and forth over what to do because the difference in price was significant, but ultimately more RAM makes for a much faster machine and it will work better, longer. It would most likely buy me another year or more of a well working machine over the Air.
Cost was definitely a factor me as well, but I was able to use the Education pricing, and I chose to buy refurbished.
Also, in terms of portability, the difference in weight is only half a pound. My roommate has the Air and I honestly feel no difference when I'm carrying hers or mine in my school bag. I'm really happy that I went with the Pro with Retina because even though I probably don't use half of the amazing features available on it, I always have the option to. Plus, not being much of a techie I have so much flash storage that I don't need to bother with my external hard drive anymore other than to backup my files. Really, really glad that I listened to the Geniuses!

Is my Apple MacBook Pro Retina a Lemon?

Brand new(7 days old) MacBook Pro Retina 2.4GHz 16GB SSD 15" with latest OS updates. I treat this MacBook like it is my newborn child. I am extremely careful with the hardware AND software configuration, almost to the extent that it's a compulsion. I have used multiple computers with Windows, Linux and Mac operating systems. I take extra time to find out the best way to treat computers as to avoid troubles like these, so I feel especially upset about losing two hours of work on my clients project. Luckily everything is backed up on GitHub and Dropbox.
I used a great tutorial from mactuts on setting up a new mac the way that developers do, and I have set up Windows and Linux just fine. I doubt there is a system or program configuration issue on my part. I was running a few programs that are not processor or RAM intensive.
- Sublime Text 2
- Google Chrome
- CodeKit (Sass compiler)
- iTerm2 (terminal)
- Dropbox (was not syncing)
- Moom (window arranging utility)
- Alfred (app and file finder utility)
There were absolutely no peripherals connected to the MacBook, no mice, USB devices, or even headphones. Only apps running.
I was typing code into Sublime Text 2 and I saved the file, watched the browser for live changes on the web site I was working on (thanks to CodeKit) and the page refreshed fine, when I moved the cursor via the touchpad back to Sublime Text 2 from the Google Chrome window, I was greeting with a 100% frozen MacBook Pro. The entire GUI was stuck, no keys would function at all, and I didn't know what to do. I searched for answers, couldn't find anything, and I held down the power button until the MacBook turned off. The computer was not hot at all during this time.
I restarted the computer after some more searching and found instructions on verifyng the disk. All is fine according to the system Disk Utilities. I just got done with a 1 hour and 6 minute Apple Hardware test with the extended testing option checked. No errors were found. The aluminum north of the function keys got SUPER hot.
The MacBook has done something similar twice before but I shrugged it off. I was doing similar tasks as may have triggered the recent problem, but the freeze only lasted seconds instead of forever. How could a 2600 dollar computer freeze during text editing and web browsing? Have I been sold a lemon? Is this a common problem? Can this problem be corrected? Can the cause of this problem be eliminated?
I have another laptop that is over 4 years old (Toshiba Sattelite) running Ubuntu 12.04 LTS. It has never had a problem running simple text editors, code watchers/compilers(Sass/Compass/Guard), or browsers, even all at the same time. From the reputation that Apple has, I was expecting more. I figured the computer might have a few hiccups if rendering a huge video file, or running 3 external monitors with Photoshop and Illustrator open and working, but definitely not with the programs I had open.
I switched to Apple to learn iOS and OSX development, to make awesome apps. I am 90% sold on taking this back to Apple and getting a full refund, never to go back. I hope someone can help change my mind and fix my computer.
Thank you so much.
Chad

Ah! A Linux user. That explains things. I wondered why you were installing a bunch of stuff I had never heard of on a week-old computer.
The bottom line is that OS X is not Linux. It may look like it sometimes, it shares a few libraries and some command-line tools, but it is completely different. Your old Linux habits will only cause you trouble.
The big question is what 3rd party software have you installed? You listed a few, but there have got to be others. It is a sad fact that OS X has zero credibility among most most corporate and open-source software developers. There is a vast amount of software that hasn't been updated in almost 10 years. How far would you get installing the latest and greatest Linux tools on a Linux box circa 2007?
As a new Mac user, you are unfamiliar with what software is good and what isn't. Some of the software you listed above is fine, but why install it if the operating system already comes with equivalent functionality? There is nothing wrong with doing that if the Apple software doesn't do what you need. But just doing it out of habit or because it is some open source project is likely to have poor results. For example, OS X version 10.8.4 was recently released. Well-written software from 2006 will run fine. Poorly written software from last week will crash, cause slowdowns, and all kinds of other problems.
If you don't have a good reason for using Chrome instead of Safari or iTerm instead of Terminal, then you are likely going to be at the mercy of 3rd party developers who have more control over your system than you do. Make yourself at home and learn your way around before you invite a bunch of rowdy kids over for a party. Later on, you can throw some parties and have fun, but you will be the one in charge. Right now, they are probably running wild in your basement reconfiguring your plumbing.
This is so common that I wrote a little diagnostic program to help show what might be causing these problems. Download EtreCheck from http://www.etresoft.com/etrecheck, run it, and paste the results here.

Macbook Pro Retina and Yosemite Video Corruption?

So I have a Macbook Pro Retina (mid 2012), 2.7ghz i7, 16gb ram, which has the NVIDIA GeForce GT 650M 1024 MB video card and integrated video. I am running Mac OS X Yosemite 10.10
I have been experiencing a lot of video corruption in different applications, it doesn't seem to be limited to just one application or two -- it is happening in Safari, Mail, Photoshop, and others.
I am attaching screen shots to show:
Here is a video when it decides to flash weird video garble:
Link to video: https://www.youtube.com/watch?v=j8RAyj9L_nQ
Has anyone experienced this same problem? is there an official name or description for what is going on? Is there a fix? It is quite frustrating.

I have the same problem with my older white Apple Wireless Extended Keyboard, which had been working fine with my 2009 iMac. But I experience the issue sporadically with my new Mac Mini. I've read reports of people resolving some BT issues by turning off "Allow Bluetooth devices to wake this computer" in the Advanced pane of the Bluetooth System Preferenes Pane.
There are also people having the issue on iOS devices using various Apple BT keyboards. No help, but interesting to note that it's happening across various devices, keyboard models, and OSs.

Photoshop CS6 a little 'jerky' when moving layers & resizing window (Macbook Pro Retina 650m)

As title says, when I open Photoshop CS6 and simple make a new layer and either use the type tool, it appears to be a little Sluggish/Jerky when moving the layer around.. The same applies when resizing photoshop itself.
I'm updated to the latest version of CS6 and have tried all the combinations in the 'Performance' section of Photoshop.
My Macbook Pro Retina is the 3.4ghz 650m and 8GB RAM offering (OS Mavericks). It's really annoying me as even my old laptop could run it smoothly and that was an i5 and much lower-end graphics card.
The only way I can really describe it (and i'm no tech professional) is when comparing it to silky smooth 60 fps, it looks like it's skipping frames and in term looking 'jerky'. I also use Illustrator and don't really witness the same problem with it.
I know this may have been asked quite a bit.. But I've never found the solution.. Could anybody advise me on what it potentially could be down too? (Might I add the laptop has just had a fresh install of the OS and a fresh copy of CS6)

You could check through the GPU FAQ for anything you might have missed
http://helpx.adobe.com/photoshop/kb/photoshop-cs6-gpu-faq.html
You say you have tried all settings in Performance, but I wonder what your cache levels are set at? If more than 1, then OK.
There's the general performance FAQ (no doubt lots of overlap)
http://helpx.adobe.com/photoshop/kb/optimize-performance-photoshop-cs4-cs5.html
Is this with all image docs, or particular ones? For instance I have been playing with using ACR to process 32bit HDR files, and it puts a huge load on the system.

Connecting 4k monitor to Macbook Pro retina 2012 mid

I tried to connect to Macbook Pro retina 2012 mid 15 inch 2.7GHZ model. Initially I connected using HDMI to 3840x2160 at 30 hz. I casually changed the resolution to 1080 p from scaled option. Now I no more get the option of scaling to 4k. I am unsure what is the issue over it. When I log into my windows. I am able to log in with my original 4k resolution in 30 HZ. Any guidance would be really great.
2) I read a few forums regarding 4k with 60hz external monitor connection for macbook pro retina 2012 mid. But I couldn't get a clear solution whether it is possible or not. Would be great if someone can show lights on this too.

1- does Apple ever do exchanges for newly released products? I bought my MacBook in jan they came out with new in mar.
If you purchased the product from Apple, not a third party, you have 14 days from the date of purchase to return it for a refund or exchange. You are well past that.
2- if and when Apple comes out with a 4k or 5k thunderbolt display, will it be backwards compatible with my MacBook sich that I can't get the resolutions and 60mhz?
I do not have an answer to that and the Terms of Use for these forums discourages from speculating what Apple may or may not do in the future. Having said that, from a practical business standpoint, backwards compatibility would be a sensible approach. It has been done so in many areas in the past.

Macbook Pro Retina Question - processor

Hey guys,
I'm seriously considering getting the Macbook Pro Retina display. I'm a graphic designer and this would be awesome for work. I'm thinking about getting the 2.6GHz and upgrading to the 16gb ram. I run alot of programs for work, basically the whole Adobe Master Suite. Sometimes I have Photoshop, Illustrator and After Effects all open at the same time so I need a powerful computer. My question to you guys is, I was considering maybe getting the 2.7 GHz processor instead of the 2.6GHz, is there a big difference in performace between the 2.6 and 2.7GHz? Is it worth the extra money to get the 2.7GHz?

for the price difference? not really worth it since it's not a big jump in speed.
if you'e going from 2.6GHz to 3GHz then I would suggest you go for it.
you're fine with the config you're thinking of purchasing.
I don't think an extra second or two in processing speed would make that much of an impact to what you'll be using it for.

Extend or replace battery MacBook Pro Retina

Dear All,
I own a MacBook Pro Retina 13' 2.4Ghz/4GB (2013) but the battery life has been terrible in the last couple of months. I probably get around 3-4 hours doing simple things like Safari on 30/40% screen brightness. The drop in battery life has been significant. MacBook is 1.2 years old and 275 cycles. I really need more than 3-4 hours.
Two questions:
1. What can I do to extend the battery life. I aim around 5 hours of usage.
2. Could I replace the battery of my MacBook?
Thanks in advance.

Well like Kappy says.
Also this is a known issue:
http://www.gottabemobile.com/2014/11/10/os-x-yosemite-problems-fixes/
"Soon after the release we heard complaints about OS X Yosemite battery life problems. The battery life drains much faster than normal for some users. For many, this is likely due to spotlight indexing after the update and using the battery faster. Typically this will resolve itself after a day or two."
They also want you to look at activity monitor.

Macbook pro retina 2013(late)

MacBook Pro Retina 2013 15" freezes when using safari

I have a 2013 MacBook Pro Retina 15" 2.7ghz, 16gb Ram with 512 gb SSD. Since the recent EFI update and the OSX 10.8.3 update, when I have been using Safari, my mac has become very sluggish and I get the spinning beachball whihch doesn't clear. I have only had this MacBook for 17 days. has anyone else had this problem?

hope there will be a fix soon…
Yours is not a common problem, and no fix for it will be forthcoming automatically anytime soon.
The symptoms you describe could indicate a failing Hard drive, and you should set all else aside and make certain your Backups are completely up-to-date.
"Any drive can fail at any time."
In cases like this, a visit to the Genius Bar is really the best solution. Your appointment at the Genius Bar for an evaluation is FREE, in warranty or out.
For problems with a physical component, or slowness problems, they have the tools and the expertise to quickly make things right. Their diagnostics also can give you the warm fuzzy feeling that the Hardware seems to be operating correctly.

Logic X on Macbook Pro Retina... "feeling hot, hot"?

I recently made an impulse purchase on a Macbook Pro Retina 2.7Ghz Quad core i7, in order to ease my transition to Logic X & Pro Tools 11. I figured with a Flash drive & 16Gb of memory that this would be a nice quiet machine... but unfortunately no. I'm quite shocked at how HOT these i7 processors run - in idle mode, the machine ticks over at 41c (istat menus), but as soon as you load a blank project in Logic X & press play, the machine ramps up to 92-93c. Consequently the fans kick in to an annoying level... & don't subside until you quit Logic. The Macbook has even touched 100c - which seems pretty hot, considering thermal shutdown is 110c. (I'm following all the guidelines on keeping the machine well ventilated, & only running it with the power supply).
I've read many similar posts in other parts of the apple forum, but I'm interested in anybody else's experiences with Logic X on a Macbook Pro Retina. Is this behaviour normal, or do I have a lemon?!! Benchmarks are impressive for the machine : 64 tracks vs 30 on my 2006 Mac Pro (Quad 3.0ghz/10.6.8/Logic 9.1.8). http://www.evan.se/logicprobenchmark/Logic_Multicore_Benchmark_Test.html
Another word of warning on Thunderbolt... it's very expensive, & you'll need it for practically everything. Once you've added a hub, cables & all the various adapters you'll need (firewire, ethernet, DVI, etc), your looking at the best part of £375/$600.... & that's not even including a thunderbolt 7200 rpm Hard Drive (£250 minimum). Sadly there's very few thunderbolt devices (apart from high end Raid HD's) that have more than one port, so daisy-chaining is not an option, & a hub is essential. Worse still, the current maximum length for thunderbolt is 3m which makes it very difficult to place a noisy mac or hard drive in another room. The new Mac Pro may be the quietest computer on the planet, but what's the point if you can't get hard drives out of earshot? (There are apparently fibre-optic versions in the pipeline that will exceed these lengths, but when?)
So folks... opinions - is your Macbook Pro Retina whisper quiet with Logic? Mine might have to go back...

Hi Mate,
I've got a non-retina MBP i5, and it's not behaving like that, so no way should yours be. Can't hear it at all until it really comes under load. But even then it's relatively quiet. Quite concerning that it's happening to you with nothing loaded up.
Something is obviously taking up cpu power just by having the audio engine running, have you checked OSX Activity monitor and checked where your processor(s) are being used?
Also, check your audio options and make sure the audio buffer isn't set ridiculously low.
Agree that Apple expansion options are expansive - However, at least they're working on getting the software reduced, Logic X being an example of that.

13" Macbook Pro Retina Specs? i5 vs i7? 4gb vs. 8gb vs. 16gb?

im not sure if i can upload these kind of questions, but i might as well give it a try. i need as many GOOD feedbacks as possible.
ok heres the thing..
I'm planning to buy a 2013 13" Macbook Pro with Retina Display soon. This will be my 2nd mac laptop after i sold my other one early because my car broke down early this year. Once i buy my mac i'm planning on keeping for well over 6 years and a little over 10 years hopefully.
Please don't tell me that computers will break down eventually because i am also somewhat tech savvy and take good care of my electronics. in fact, I first macbook ran very well that i was planning on keeping for a very long time as usual with apple products. unfortunately i had to sell it because my car broke down and needed the immediate cash at that time.
This is very important to me for my future as im also still in school trying to finish up. So I'm asking as many different opinions as possible and please be specific. for ex.: You should get the i7 since it will benefit you for the long term and you will feel the big difference even in small internet tasks and watching HD movies.
don't just say get an i5 for example, tell me your opinion why certain specs will be good enough than the other. Simply, Compare and contrast.
I know this was long but i'll get the point of the question..
My main question #1: Are there big differences between the new Haswell i5 2.4Ghz & an i7 2.8Ghz for what I do on the computer?
My main Question #2: Is it worth getting 4gb ram or 16gb ram?
To Finalize: Are all these worth my money for what I am going to use it for and length of time?
here are the list of models..#1 specs indicates my first choice whether or not it will be worth my money? (If its worth it, I am willing to spend up to almost 2k.)
1) 13" Macbook Pro Retina 2013
Haswell Intel Core i7 2.8 Ghz 16GB DDR3 Ram, & 128 SSD
Price: $1,899 (Configured & Shipped)
2) 13" Macbook Pro Retina 2013
Haswell Intel Core i5 2.4 Ghz 4GB DDR3 Ram, & 128 SSD
Price: $1,299 (In Store)
FYI: I am fully aware that the new retinas are non-configurable in the future which I'm totally fine with it.
Ok heres how i'll be using my macbook..
Internet, movie/tv show streaming, some light media downloads for entertainments for personal pleasure, watching 1080p movies and shows. (I multi task a lot too, but I never game nor i use photoshop and other intensive applications.) i very rarely sometimes use photoshop though but it would be just merely just for fun and messing around.
as for school and other work related usages are...
im a sociology major and plan on teaching elementary level kids in the future and maybe? open a small business with my own specialties but teaching would be my main long term goal.
I look in the long term and i want a quite speedy computer. I fully know the base model is also more than enough i need but once again for the speed. plus, smallest 128 SSD is always enough for me so no worries about storage space.
once again i need as many GOOD feedbacks as possible as this is important to me and my budget. and please be specific of what you say. thanks
So would the #1 choice of my macbook pro be totally worth my 2ks? Are there a huge difference between an i5 2.4 & i7 2.8 that i will totally feel while using my mac on a daily basis?
