2.4GHz versus 2.53GHz

I own a late MBP 2.4GHz. I want my laptop the fastest and most efficient possible. Would the 2.53GHz have made that much difference? I'm using mostly now for surfing the internet. How can I increase performance? Memory or hard drive?

MacBook Pro 13,3 and 15,4 : graphic memory

I would like to buy a MacBook Pro but I'm worried about the graphic memory. On the MacBook Pro 13,3 tech specs I can read:
"NVIDIA GeForce 320M graphics processor with 256MB of DDR3 SDRAM shared with main memory"
Shared? Does this mean that the video card hasn't got dedicated RAM?
On the other hand in the MacBook Pro 15,4 tech specs I can read:
"NVIDIA GeForce GT 330M graphics processor with 256MB of GDDR3 memory on 2.4GHz; Intel HD Graphics with 256MB of DDR3 SDRAM shared with main memory"
Please could you explain me what does they mean with "shared" memory?
How about performance? Usually NB has a lot more video memory such as 1GB...

As I wrote above, I've been doing lots of work in Adobe CS4 applications using the integrated GPU and *its 256MB of "shared" RAM (not really shared, because only the GPU can use it)*. I have 4GB of RAM installed, and I'm getting my work done just fine in 3.75GB of it.
If nothing we can say will reassure you, then you'd better buy some other computer.
Precisely. It appears that the integrated graphics engine has 256MB of dedicated memory available, but it's advertised as "shared" because it comes from the (main) system memory. In reality, it's not the 256MB of graphics memory that's being "shared", it's the 4GB of system RAM that's being shared
And 4GB is plenty of RAM.
Also consider this: the discrete graphic cards available on the 2.4Ghz and 2.53Ghz 15" MBP come with 256MB of dedicated RAM. Only the top two configurations have 512MB of RAM available (the i7 15" and the 17" models).
You should be fine.

Could wifi with a university network drop often because of a 5ghz band connection?

Hey guys,
I've been having wifi issues at my school/work (same location) with the connection dropping randomly. It seems to happen several times an hour. I purchased a MBA months ago and had no problems with wifi connectivity till recently. My school has acquired a new access point in the facility. It was right around the release of Mavericks. So now I've become unclear on whether it's the network or the new OS. Anyways, the network is WPA 2 enterprise with dual-band connectivity. This past week I have done my fair share of studying on dual-band technology and now understand perks and downfalls to 2.4ghz versus 5ghz bands. That reading was due to a connection issue at home. However, today I finally realized that I was connected to the 5ghz band at work/school by using the option key and clicking the wifi icon. After browsing through several forums, I was still unsure if A) the 5ghz band was responsible for wifi dropping, and B) Whether or not I could disable the wifi from defaulting to the 5ghz and use 2.4ghz as a solution instead.
Since I could not find answers to those two questions I have tried the following...
I changed the MTU to "1453" since it's the so-called "magic number" for mac's. And yes, so far it is the magic number because the wifi has not dropped once since applying it. I'm still standing by, convinced it will drop. Wireless diagnostics is currently monitoring if it does. Typically I use the ethernet adapter so I don't have to worry about any of this. That's a fix, but not the one I'm looking for. It's flat out annoying! I know I can try renewing the DHCP lease as well. I haven't done it yet because I'm seeing if the MTU was the sole source of the problem. I've already performed basic troubleshooting and like usual it didn't solve anything. That's not to say that restarting doesn't cover a higher percentage of issues!
Honestly the MTU change could be the end of my problems, but I'd still like some insight on my two questions in the first paragraph. Any guidance is strongly appreciated. I've been loving my mac and the community since I made the switch not too long ago. I'm just still familiarizing myself with everything. Thanks in advance for any help!

That's correct.
When it's unable to obtain an IP address from a DHCP server, machines are supposed to self-assign themselves an address from the 169.254.x.x range.
This is so that you can, for example, connect two machines with an Ethernet cable or via Wi-Fi without the need for a DHCP server and the two machines will be able to talk to each other.
(If you care, you can read the technical details here.)
So the big question here is why your machine is failing to obtain an address via DHCP, and it sounds like an issue with the DHCP servers on your network.
If you want to read more than you probably would ever want to know about how one campus is dealing with similar issues, you can here.)

Is anyone else having iPad 2 wireless issues?

I'm on my second iPad 2, the first one had issues staying connected to my airport extreme and had very slow download and upload speeds. The apple store replaced it and the second one seemed to stay connected fine but was still very slow on the internet compared to my iPhone and iMac. I use Speed Test and have repeatedly seen very slow speed results when testing all three devices one after the other. Now it seems that the issue with connectivity is getting worse and the speed test remain very slow in comparison. I did a test on my iPhone today are got very fast speed and the iPad 2 wouldn't even connect to the wireless. This is very frustrating as I decided to spend the extra $ for the wireless feature. Anyone else having these issues and what would you do? Any fixes or updates coming soon from Apple? Love the devise otherwise.

My iPad2 has recently experieced dropped connectivity problems as well. At first I thought it was an issue because I just got my wife the 4th gen iPad and as soon as she started using it I started having these problems. I can connect if I'm sitting next to the router (Time Capsule), but if I move out more than twenty feet the connection gets weaker and eventually disconnects. This only happens with the iPad2, my wife's original iPad still maintains a strong signal as does her new one, same with all the MacBook Pros we have. It's not the router since I have tried it with others with the same result.
I have done all the suggested steps by Apple User Maunual and by Discussion groups members
1. rebooted the iPad2 and Time Capsule
2. Reset Network settings
3. Established separate channel 6 for 2.4ghz versus 5.ghz
4. Shut off Auto- Brightness and turn up Brightness to full.
5. I even wiped all the data, apps, etc clean and started over.
I still have the problem. Quite frustrating to say the least. There still may be an issue between 2.4ghz devices and those that are also 5.ghz, but I haven't solved it yet. Or maybe it's a hardware antenna issue.

IPad 2 hangs, is slow, loses ATT wireless. Restart usually fixes, but frustrating

After updating to iOS 8 yesterday, I have lost service (3G) twice, necessitating a restart. All apps work slow, even iOS itself. Sometimes I think I haven't touched an icon correctly, so I reach for it, and it finally reacts. Is it possible to go back to 7? I wasted over 2 hours updating to 8, but I am willing to invest 2 more to go back to 7.

Last Years 15-inch 2.53ghz vs This years 15-inch 2.4ghz Macbook Pros

I purchased a new 15-inch MBP last year (the base model with the 2.53ghz processer, 4gb ram, etc.). I saw they recently released the new i5 processors for the MBPs, however, I noticed the new base model only has a 2.4ghz processor. In the past I have upgraded my computer every year, but I need some convincing why this new i5 2.4ghz processor is better than my current last year's model 2.53ghz.
I already have the non-removable battery. The ram has not changed. Nothing else seems to have changed much...unless I am missing something.
Please help with any suggestions. Thank you!

In the past I have upgraded my computer every year...
If you've been in the habit of doing that, and you still have the bottom-end 15" MBP of the last generation, then you must be well accustomed to seeing very little bang for your upgrade buck. If you were to do it again now by buying the bottom-end i5, that very small increment of benefit would be repeated.
I can (just barely) understand someone who feels a real compulsion to be out on the bleeding edge all the time upgrading his or her computer annually, but for someone who obviously doesn't have a burning psychic or practical need to own the whizziest whizbang on the block, it seems like a real waste of money to upgrade every year from the bottom of the old line to the bottom of the new one. I strongly recommend that you wait at least another year, buy a midrange new machine, and plan to upgrade it every two to three years instead of annually.

2.1GHz versus 2.4GHz

Ok, so to put it plainly, I had my heart set on the 2.4GHz white Macbook but managed to stop myself from buying and convinced myself to wait for the new ones to come out.
Now, obviously, the model which I was going to get is no longer available, only the model with the slower processor. I have no real desire to go with the new Macbooks. I use FireWire, I don't particuarly love the design and they're a good deal more expensive.
My question is, do I now settle with the 2.1GHz white Macbook (with improved RAM and hard drive capacity), or do I try and find an old 2.4GHz model? Is there a noticeable difference in performance?

You can never have too much RAM! If I were you, I'd buy the new white MacBook with your discount and start with 2GB of RAM. You can easily add more RAM yourself and you can almost always buy more RAM for significantly less than Apple charges. If you feel the 2GB is not satisfying your needs, you can upgrade to 4GB on your own. RAM will not necessarily make things run faster. It will allow you to do more things all at once than you could have without a performance hit, however.

MacBook pro 15 inch Hard drive noise - 2.4ghz vs. 2.53ghz

Hi,
I finally re-purchased a mid-range MacBook Pro 15 inch (500hd, 2.53 ghz). I had first bought it in September from the online store but it was scratched right out of the box and the bottom panel wasn't put in properly so I sent it back.
Anyways... I turned the new one on yesterday to find that the hard drive was very VERY noisy (in my opinion). I could hear it running (like whoosing air) while the TV was running from across the room. It was much much louder than my 4 year old MacBook (it's dead silent except for when the fan gets going), and much louder than both of my parents last gen MBPs (you can hear the hd in theirs but only very close to the computer).
I took it in today and they said it was normal, all hard drives are different, yada yada yada. They gave me a new one, but I haven't opened it yet because I want to know whether a low end 15 inch (2.4ghz) would be quieter than the 2.53.
My question is: *Would the low-level 2.4 ghz be any quieter than the 2.53 mid-level? Should I downgrade to the 2.4 or should I just accept that any MBP I get will be louder than I'd like it to be?*

Thanks for the description. My old (and I think my dad's MBP) has a Fujitsu, and I'm pretty sure the MBP I returned had a Toshiba HD.
I'm wary about opening the box because if it is noisy I'll have to pay the obscene restocking fee to return it. I suppose the only way I'll find out the noise level is to turn it on though.
I was thinking that if it is normal and it's just too loud for me, I could return it, swallow the fee, and just get the cheap MacBook. That may still make noise I'd still end up saving over $1000...
Anyways, if the general consensus is that they just make noise I'll have to open the box up and test it out and see if I can live with it.

New Computer: iMac versus Mac Book?

I am going to soon replace my over 5-year old iMac Power PC,800 Mhz, 256MB Ram).
Although I do not need it for travel, I am considering a Mac Book only for the space saving on my desk at home.
What is the functional differences (other than the obvious screen size and hard drive size) between the 13 inch Black Mac Book:
2.4GHz Intel Core 2 Duo
2GB 667 DDR2 SDRAM - 2x1GB
250GB Serial ATA Drive @ 5400 rpm
SuperDrive 8x (DVD±R DL/DVD±RW/CD-RW)
and a 2.4 Ghz iMac custom configured with 2GB of RAM?
2.4GHz Intel Core 2 Duo
1GB memory
320GB hard drive1
8x double-layer SuperDrive
ATI Radeon HD 2600 PRO with 256MB memory
The Mac Book doesn't specify video memory?
What else would I give up other than screen size (13 inch versus 20 inch)
and hard drive size?

Video memory is integrated with the Intel X3100 graphics chipset. It uses a part of the main system memory (I believe at least 144MB [or more] although it may be fixed in firmware).
What else would I give up other than screen size (13 inch versus 20 inch)
and hard drive size?
Graphics performance is probably going to be the biggest issue. Hard drive speed is going to be better with a 3.5" 7200 RPM drive.
I've got a MacBook myself. I use it on a coffee table. It may not have all the features, but it certainly equips itself well for what I want out of it.

2.26GHz vs 2.53GHz for music software?

I'm getting a new MBP 13" to replace my stoneage-y PoweBook. Can you help me choose between the two models?
- I'm a musician, mainly using the software Ableton Live and Reason for recording and composing. In Live, the built-in synthesizers will not run smoothly on my current machine (1,33GHz and 1GB RAM). I want to avoid getting this problem again, but don't know if it's due to RAM or processor or something else.
- I also do some webdesign and work in Photoshop, so I guess I would upgrade to 4GB RAM anyways, however, the price difference between the two models even if I upgrade the lower end one to 4GB is still $200 or something like that.
- I'm not worried about the size of HD, as the 160GB in the lower-end model is enough for my needs.
Question:
Based on this, can anyone advice me: Is the extra processing power in the 2.53GHz model worth the cash? I'm more concerned about the music creation sw than the graphics.
Thank you!

Scroll down to the bottom where they compare the performance of the Macs. If you notice, the difference between the 2.8 and the 2.26 is minimal. I imagine the difference between the 2.26 and 2.53 to be even less. I'm a gamer and use a desktop with Win XP and a core 2 duo 2.4ghz and the CPU never slows me down even with the less efficient OS. Something to keep in mind is that CPU performance does not rely souly on the frequency. CPU architecture, front-side-bus, and cache can make a big difference between CPUs at the same frequency. A 2.4ghz pentium IV, core 2 duo, and Athalon x2 so not all perform the same even though they have the same GHz. When comparing these new CPUs, they are all the same architecture and have the same front side bus. The 2.8 has more cache than the 2.26 and 2.53 so it'll be noticeably better, but the 2.26 and 2.53 will be so similar that only a benchmark will show you a difference.
Now for a simple explanation. The 2.26 and 2.53 will perform nearly identical. The difference will only be noticeable if you run benchmarking software (3dmark or futuremark). I would not pay more than $50 for the jump in CPU performance seen here. For $300 you could push your system to 4gb RAM and get a larger HDD and it would be more useful than the jump in CPU. If money isn't an issue then go ahead, but I don't think it's worth it. If cnet benchmarks mean anything to you, you will see that there's minimal difference.

New Iris graphics on newest MBP 13in 2.4ghz fast enough? Any lag?

So I've been googling my heart out trying to find anyone who has bought the new MBP 13in 2.4ghz (any ram/hdd combo) and reported on this or not, and have yet to find any that didn't say "it SHOULD be totally smooth" (or the like). I bought my first MBA in September, but then found out about the October event, so I returned it in case the new MBP fit what I wanted better (although the battery life was absolutely amazing on the air).
The final decision maker for me between buying another 13in Air, or going for the 13in MBP, is if the new Iris graphics can push the retina display without lag consistently. I read about the 2012 retina models with the intel 4000 onboard graphics lagging for people due to it not being powerful enough. I prefer the 13in model because it's size works best for what I need, and both just fit into what I can afford, so the 15in is off the table.
Can anyone who has purchased the based MBP model comment on if the scrolling and general experience is smooth, or if they are experiencing any lag? This will be my first macbook, and want the best experience I can get (for what I can afford obviously). If the base MBP isn't strong enough for retina, I have no problem getting the Air with amazing battery life and still good screen quality, but I believe at 9hrs of battery and retina, the new MBP would fit the perfect balance for me of battery vs display quality.
I went into the apple store yesterday to judge for myself if retina makes enough of a difference to make it a second option (versus just getting the Air), and the retina is beautiful. I thought the Air's screen looked great until I played on the retina for a bit, the colors look great, and for some reason, I've very anal about the quality of my fonts, and they just looked amazing on the MBP. The reason I have turned to the community here is that, sure I did some very minor testing, but a little while in the store going through their demos isn't quite the same as someone who has used it for days in real life. Obviously I can return one if I'm not satisfied and get the other, but who wants to get a computer setup the way they want, only to run into problems and return it a few days later.
If this has been asked already, I apologize and if you could point me to that thread, I would be grateful.

You should also ask this in the MacBook Pro forum. This is the forum for the 13” white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

MBP 2.4Ghz Penryn Magsafe LED light randomly on/off w/ sporadic charging

I have one of the February 2008 MacBook Pro's with 2.4Ghz C2D. I have had this thing for only 5 days and have noticed that the charging behavior has been sporadic.
Sometimes i plug in my MBP and the amber light illuminates to indicate charging, and 10 minutes later, the light is off - no light, not even green is illuminated. But the MBP indicates that it is plugged in and charging on the menu bar, as well as flashing LEDs on the bottom of the MBP/battery pack.
I have also noticed that sometimes when I plug in the MBP and place the computer in sleep then return many hours later, the LED on the magsafe is not illuminated at all, and the battery is still drained around the same amount as before I plugged it in. This has happened three times so far. This is an intermittent problem and not reliably reproducible.
I have already tried resetting the SMC. I guess I will call AppleCare... Anyone else have this problem?

That sounds like a faulty power supply unit ...

Upgrade WXGA+ Mid-2010 15" 2.4GHz i5 MBP to WSXGA+ Antiglare possible?

Hello fine folks,
My girlfriend recently had an accident with her Mid-2010 MacBook Pro, and the LCD panel needs to be replaced.
Unfortunately, it was purchased in haste and as such, it's a base-configuration 15" machine with the glossy 1440x900 screen, and lowly 2.4GHz i5. Further, AppleCare was not purchased for the machine and the original warranty is a thing of the past. In any case, it has been upgraded with 8GB of RAM and a 500GB 7200rpm hard drive, making it a perfectly serviceable machine, if not an absolute screamer.
Given that we now need to replace the LCD, I'm wondering if it might be possible to kill two birds with one stone and upgrade to a high-resolution 1680x1050 LCD at the same time, preferably Antiglare.
I imagine I would need to acquire a whole new clamshell from an Antiglare model. Assuming I could come across such an item, would it be as simple as removing the old clamshell with the broken LCD and installing the new clamshell? Would there be any incompatibilities between the existing logic board/display subsystem and the high-res LCD panel?
I am perfectly comfortable doing such surgery myself.
Many thanks for any input/experience!
Bests,
--Jeff

Certainly not... but I'd rather source a complete antiglare clamshell lid and slap it on myself thus upgrading the machine, as long as I know I wouldn't have to replace the logic board as well... I've done plenty of surgery on notebooks, from removing a stuck business-card shaped CD from a 12" PowerBook G4 (requiring *complete* disassembly of the machine) to swapping ThinkPad T61 motherboards into T60 chassis creating a 15" 4:3 IPS FrankenPad which can take 8GB of ram... so I can handle swapping a display.
Local apple store hasn't told me clearly whether or not it's possible, just that they will only replace it with the original screen...
I can only find one logic board part # for a 2.4GHz mid-2010 15" MBP, which suggests to me that upgrading the screen should be no problem, but I'd love to hear from someone who's done it or can give a definitive answer as to whether or not it's possible...

MBP mid 2010 - 15" 2,4Ghz (Battery Problem)

Hi guys.
I have a MBP mid 2010. My battery wont last more that 4.30 hours.
I have tried more than enough times to test' it.
Last Night with fully charged battery I was able to get 4.40 Hours.
Bluetooth OFF
Low monitor brightness
Low keyboard illumination
Air Port was on.
Basically web browsing and 4 or 5 youtube videos.
Did not make any software instalation or updates.
4.30 hours its just to low.
BTW it as 37 full charges
My work laptop wich is a Dell Latitude E6400 with a 9cell battery I get more than 5 hours. And it as way more full charge cycles.
