Help a Mac newbie choose - 21.5" i5 or i7?
Hi Guys,
I've been a PC user since the middle ages (not really - 1995 to be exact). I've finally decided to buy a new iMac as I love the simple intuitive nature of the OS. I already own an iPhone 4 and an Apple TV. I love them.
So, it boils down to this. I love the look of the 21.5" - the 27" looks awesome, but I don't have the space for it in my study. My computing requirements are pretty simple; I'd love to be able to have full functionality using: iLife, iWork and iTunes. I currently have:
*about 5,000 songs on iTunes
*11,000 photos and maybe 50 short HD video clips (I use a Canon 550d, capable of 24ffs 1080p)
*a few GB of MS Office documents.
*a 500Gb external hard drive.
*a €2,000 budget.
So, the questions!
a). Will the entry-level 21.5" suffice for my needs, given that I already have a 500Gb external hard drive?
b). Will its 2.5ghz i5 chip run all my apps smoothly, especially 1080p 24fps video clips from my Canon (this is the main reason I'm buying the iMac)
c). Is 4Gb RAM and 500Gb of storage *really* enough, or am I selling myself short for future proofing the machine?
Thank you all for your patience with this Mac newbie!

Frank,
The 21.5 is way more than enough for your needs. You should investigate a couple of things though, first you will need another external HD to use as a backup. Operating without backup is a roll of the dice, get yourself a good quality 1TB drive and you should be set. You can use this for Time Machine, if you're not familiar with TM yet watch Time Machine Tutorial, it's only a couple of minutes long. You can easily find a very high quality 1TB drive in the $100 range. The only brand I'd steer away from is Western Digital, they tend to not work well with Macs.
Start out with 4GB of RAM, if this proves to not be enough upgrading RAM is a 5 minute job, inexpensive and doesn't affect the warranty. You can upgrade to 12GB for as low as $76 which provides a lot of headroom. If that is of interest visit OWC at www.macsales.com, they specialize in Macs, have good prices and excellent support including "how to" videos.
In addition I'd also recommend getting AppleCare. This extends the warranty to 3 full years and provides 3 years of telephone support.
Finally I'd recommend bookmarking and visiting:

I need to buy a MacBook Pro for my son--it's required for the advertising graduate school he will be attending. I am only familiar with PC specs--so I'm not sure how many bells and whistles we need to put on a MacBook Pro to make sure it performs with no glitches. My son will be using this computer for photo and video editing, page layouts, website production, copywriting, and general personal use--iTunes, etc.
First question--2.4 GHz or 2.6 GHz processor? Do we need the fastest processor for video editing?
Second question--2 GB or 4GB of RAM? I've read that Macs handle memory much better than PCs. We need a minimum of 4 GB of RAM on our PC to handle video editing functions. Can we get by with 2 GB on the Mac?
Third question--Final Cut Studio 2 or Adobe Premiere, et. al. for video editing?
Finally, can you truly edit video on a laptop with an external hard drive connected? (If so, should the external hard drive be firewire or is USB okay?)
I appreciate any and all advice from experienced Macbook Pro users!
On Edit: Which screen glossy or flat? I'm truly not sure which is better for his needs.
Message was edited by: samdogmomAs someone who works in advertising and instructs at an advertising school, I would strongly recommend against the glossy screen. It may look better at first glance, but that's because it tends to blow out contrast a bit. The matte screen will give you something that is not only more accurate but more reliable to calibrate with when you're trying to make what's on your screen match exactly with a production press or even regular printer.
Regarding the other questions, I think the processor speed (2.4 or 2.6) is mostly preference and cost. If you can afford it, it will help him when video editing or when working on a 500 mb photoshop file.
I'd definitely go for more RAM. Right now, Final Cut is simply more pervasive. That may change in the future, of course. Hopefully by then, either he or his future employer will be flipping the bill.
As far as external drives, you can indeed edit video with one and I've had many people warn me against using the internal drive if you're doing really heavy duty editing (it works fine if doing a home movie or personal project). In this case, get a Firewire 800 drive. For truly superior performance, he should consider a very fast RAID setup. If editing an uncompressed Quicktime file for example - a :30 commercial will usually be around 1 gigabyte - most computers and drives aren't even able to play such a file. It will play with extreme stutter if at all if you're using your internal drive as your scratch disk. My guess is he won't be working with files as big as these, though.
Now I will offer one word of caution on all this. I'm not sure what your son is intending to study (copywriting, art direction, graphic design, video, web design, etc.), but you really don't need all this power if, say, he's studying to become a copywriter and is going to be taking one video editing class. Of course, if money is not an issue, the more computer muscle the better. Waiting for video to render or for a photoshop filter to be applied to a megalarge file can never be too quick.
Sorry for such a long entry. Good luck to you and your son.

I just got my first Mac two days ago. I bought a duo core iMac used off eBay. I love it so far, and I felt I got a good deal as the guy I bought it off of left his whole iTunes library for me to enjoy.
Anyway after I uploaded all my cds into iTunes I updated the firmware, as it had kept popping everytime I logged back into Mac OSX.
After doing so I was shocked to find that my iTunes library and all my personal settings in firefox etc... were gone!
All the files are still there but I was wondering why this happened, and if there was way I could just roll back te update or something (I think thats what they call it in Windows). Or if there was an easy way to get my same iTunes library back, as there are many duplicate folders and cds on here for some reason.
Thanks for any helpgter you double click on your hard drive icon you will see a little house at the top that says "home" click on that and you will see a music folder. Click on that and you will see an iTunes folder. Click on that and you will see an iTunes music folder. Click on that and you will see all your music songs. I've found out where my songs are that have an exclamation point by them. I open the library window and drag that song and plop it in it's appropriate place in my library. Then I delete the exclamation pointed song. Now, there must be a way to take them all at once and stick them in your library. Maybe u just drag the folder iTunes music and plop it down in your empty library window. Anyone know?

Yet Another Hard Drive Question from a Mac Newbie
I apologize in advance for the length of this post -- as I state in the subject line, I am a complete Mac newbie.
I just took delivery yesterday on a new (early 2008) Mac Pro. I purchased and installed an additional 8GB RAM, and ordered it with a 500GB HD (Seagate, it looks like) and purchased two 750GB Hitachi HDs for bays 2 and 3. I will be doing a fair amount of photo editing, and also plan to partition the OS drive to run XP using bootcamp, but also plan to use VM Fusion.
I am thinking of partitioning the boot drive with 250GB for OS X and apps, 150 GB for XP and apps, and ~66 remaining possibly to be used as scratch memory for CS3, though it sounds like this may not be enough. The bay 2 Hitachi would be used for all my user data (photos, music, docs, etc.) bay 3 would be for backup initially, possibly using Time Machine? (other recommendations welcomed). As space becomes an issue in the future, I will invest in a fourth internal HD, and at least 2TB external HDs for backup.
Does this seem like a reasonable plan? If so, how do I go about formatting the drives and installing boot camp, Fusion, etc., and in what order? Also, how best do I organize my existing files from my current Windows machine as I copy them to the new user data HD, so they can be accessed as needed by both OS X and XP?
Thanks for your help.I like the boot volume to never get beyond 50% used. Enough room for burning dual-layer DVDs can be 50GB for best results. And to force the system to use the first outer tracks.
I hope you are concurrently zeroing both drives. SoftRAID is my choice for driver for RAIDs and you can cancel safely at any time. There are also excellent tools for checking sectors and mapping out bad blocks.
I put Vista on its own 10K Raptor. I had it on the boot drive but I am always changing my mind, my drives and setup. Vista needs at least 40GB and that is with all my major documents and files on another drive which holds 150GB out of 450GB.
You set the preference for what drive to use as scratch in CS3 or other programs. And you want to disable Spotlight indexing on any scratch or editing partition. Scratch can be a drive, a volume, a stripped array. Any 'normal' partition though don't use the default (journaling) feature is all.
How large? I'd have to see and know how large files, work flow, and how long you work between projects. The nice thing, erase the scratch volume between projects but it is possible to use 300GB when you work on 1.5GB files and above.
One early Mac Pro owner wasn't able to work as they wanted until they had 10-12GB RAM, boot RAID0, and RAIDs for scratch and data (saving 2GB files and not having to wait forever, which even a minute can feel like forever).
Disk Utility: Partition. You can even partition 2+ drives, just make them the same, and first create 2 partitions (100GB on each?) and then stripe the first "Untitled 1" of each into 100GB x n array. Stripe or mirror the "Untitled 2" or leave those are two unique non-RAID volumes. Sounds harder than it is.
Scratch = temp space and designed to not be saved, to be erased as needed.
SoftRAID.com 3.6.6 makes it easy to create, delete, erase volumes and arrays as needed. Leopard has improved on non-RAID but not with RAIDs (for those that change their minds). -
I was really looking forward to kicking Windows into touch. No more virus software, no disk defragging required. Simple Tiger operating system. Fast performance. Throw in a Mac Pro and I should have been full of joy.
The reality has been pure frustration. I found I had to dual boot to windows to make so many little jobs I do as routine work on the Mac Pro. Boy is Tiger lacking in so many areas. Mac Mail or Entourage are just so dated and frustrating to use. Office 2004 for Mac - well come on guys, does it really have to be that creaky? Compared to the Windows version, and the latest Office 2007, it is really so limited. Can't compress pictures in a document, for example so have to send larger folders with pictures in as a PDF.
The performance of Adobe Photoshop CS2 for Mac should have been stellar. Nope. Thrashed by CS2 running on my 4-year old IBM Thinkpad laptop; the programme did storm through work in its Windows version on the Mac, but you do not by a Mac to run Windows full time do you?
Much as I want to join your club it will need a few changes. Like simple, affordable personal finiance software that allows easy migration for MS Money. Or an email programme that allows you to list contacts by first or last names. Or a system that allows you to turn off certain toolbars and keep them turned off. Software that allows simple routeplanning to be made. The ability to run RAW picture conversions without locking up. Safari allowing personal data to be stored, so allowing access to multiple on-line bank finance mangement systems from one site. Support for keyboards that help those with RSI. Ditto with track balls. Or even a few more printer drivers; failure to work 2 out of three of my printers, the oldest of which is 2 years, is not encouraging.
I could go on. In fact I did - I spent over 50 hours just trying to make a working system of of a Mac and OS.X Tiger operating system. It just could not be done. I even tried doing it the Mac way for five solid days. It was like going back to an abacus.
All in all I am just so dissappointed. My 2 weeks with an Apple Mac has shown me the grass is not greener on the other side. Windows XP may stink - Vista is too dreadful to even consider - but the Tiger was so tame I won't be coming back.
Mac Pro Mac OS X (10.4.10)
Mac Pro Mac OS X (10.4.10)As another Mac newbie I thought I'd share some of my frustrations with OSX, but also why I won’t be returning to windows anytime soon. I've built PC's for almost 7 years, so I know exactly how much flexibility you have in both building and operating a windows PC. I also know the exact definition of compatibility. Thousands of different manufacturers making parts for PCs is a nightmare, if you don’t believe me build a computer, I dare you. Over my years building computers I have pulled out more hair, lost more files, and nearly broke so many parts I prefer to not talk about it. So finally when it was time to upgrade I thought about a Mac. Problem was I wanted a computer that had some flexibility in terms of upgrading. I was absolutely blown away by the cost of powermacs. I could build a new PC, no exaggeration, for well less than half of what a powermac would cost me. Not to mention a powermac g5 was already a generation old. So I caved and bought a dell for dirt cheap, cheaper than even what I could build a PC for. Not only that I thought maybe vista is a savior so I got my new dell with windows vista. Lets just say my brand new computer (I bought the dell in February) ran drastically slower than the nearly 6 year old computer it was replacing. Not to mention I had to go buy a new wireless card, and most of my software didn’t work. Vista looks pretty, actually it looks just like OSX, but it runs terrible unless you have a top-of-the-line computer. Anyway to make a long story short someone on craig’s list was getting rid of their powermac and they needed a new windows PC so we traded. I also recently bought a powerbook g3 so I’m 100 percent Mac now. I’ve been using OSX for a few weeks now and I’ve read some articles on making the switch. I’ve found how incredibly easy OSX is to use and how intuitive many of the features are. There are a few downsides to using a Mac I certainly understand. One is the lack of software support. I regularly use Reference Manager and SPSS, two programs that are unfortunately not supported in OSX. However I normally use these programs at work, so for now I can go without them at home. I suppose there are two other complaints I have about Apple and Macs. I’ve found that first, Macs don’t like non-Apple parts. Buy a third-party anything and you’re in for a headache. Second, what was common knowledge on a PC means nothing on a Mac. Installing an airport card took me more than a day because I didn’t know what I was doing and my mind was still thinking windows. I’ve been frustrated more than a few times with my new Mac, but the problems have been entirely because of my naïve understanding of Macs and OSX. All in All though I completely understand that Macs aren’t for everyone, especially people who use a lot of professional software. For me though the choice is easy, I want a computer that is easy to use, does basic tasks, and for the love of all things holy doesn’t crash and lose my data. Everything after that I will learn to cope with. For these reasons I am sticking it out and learning the full feature set of OSX.

Hello. I bought a new iMac 27" with the following specs:
3.5GHz Intel Core i7 Quad-Core (Haswell)
32GB of 1600MHz DDR3 RAM
3TB Fusion Drive
NVIDIA GeForce GTX 780M Graphics (4GB)
27" LED-Backlit IPS Display
2560 x 1440 Native Resolution
802.11ac/a/b/g/n Wi-Fi, Bluetooth 4.0
Thunderbolt, USB 3.0, SDXC Card Reader
720p FaceTime HD Camera, Dual Mics
Mac OS X 10.8 Mountain Lion (64-bit)
After installing all Mac update, used Bootcamp to create a Windows 7 drive. Everything went fine to a point. While in my Mac OS i can see the windows partition just fine and see/edit documents. However, when in the Windows 7 Pro 64 bit, I cannot see the mac os in my computer at all.
Can someone please help this mac owner newbie? This process worked fine on my mac mini and i have no troubles. It is just on my new iMac that it wont work/show the highlighted paragraph above
Any ideas and/or help would be greatly appreciated.I understand that much. On my MAC Mini, if you look above at original post, I CAN see both OS while in the Windows 7 partition or the MAC OS. This is NOT the case on my iMac. Again, when in the MAC OS I can see the windows partion and move information between the two that way. When in the WINDOWS partition, the only one that shows is the Windows OS from my computer or network. The only way you can tell its even a MAC is the bootcamp icon in the bottom right corner of toolbar. Both have same version of MAC OS so both should work same way.. When i double click on my computer, it should show both the Windows drive AND the MAC (as does my mini and another iMac 21.5 that i have). This iMac does not do that - only shows windows.

Mac Newbie TM & Spotlight issues
Hi All,
I got my new iMac on 21 September 2012. I have a NAS (Network Attached Storage) drive on my Netgear DGN 2200 router which Spotlight never really managed to index - it always estimates a huge amount of time and even if I let it go it doesn't get it done.
When I started TM backup it extimated about a month and I let it go because I thought it would figure out that it was a new / empty machine quite quickly and the estimate would come down. After two days and only 2-3GB backed up I stopped it and deleted all of the backup data and started again. Same issue.
Then I turned off spotlight and eventually got a week-long backup done.
I then updated to 10.7.5 supplemental upgrade which apparently fixes long TM backup issues.
Now, with spotlight turned back on TM has been taking forever with its incremental backups. For example, I turned it on an hour ago and opened pages & Chrome, then it started a backup 50 minutes ago. It says "Backing up: 116.6 MB of 116.6 MB" but it's still going 50 MINUTES later!!! update: 75minutes later
Spotlight is still not indexing my external storage which is an issue because I have all of my work on the external.
I have been trawling through this forum but being a mac newbie I don't understand all of the jargon - sudo this and that, and if I get a solution it does need to be step by step. I have always been tinkering around under the hood of previous M$ machines and would be a 'power-user' so I'm not stupid but it's a whole new language for me.
Should I upgrade to Mountatin Lion?
Is there any way I can downgrade to 10.6?
Is there any way to search without using spotlight? On the pc I used to be able to search non-indexed locations, it would just take a little while.
Time Machine is not trying to backup my NAS drive is it? From my understanding it doesn't do that but maybe it's confused ... ???
Thanks for your help.I don't use raid myself so I'll leave that explanation to others. I configure my Mac Pro with 4 drives. My main drive is my boot drive and has about 300+ gigs free. I have a backup drive for that which I use SuperDuper for backup, creating a fully bootable backup drive in the event my main drive has a problem. I only back up to that drive when my machine is "good and solid". That allows me to throw on the most recent update without much concern. If there is a problem then I just boot from my backup drive and I'm back up and running just fine. I also use the backup of my main drive for my Final Cut Pro scratch drive. I copy the files for my movies to external drives for archive when needed. For my data drives I use another set of 500 gig drives. One for data (mostly photos) and one to backup using superduper whenever I feel like it. You could automate it all with Retrospect for the data drives if you wanted to. I don't think Retrospect will make a bootable backup of a main drive. I use Western Digital WD5000KS ddrives, 500 megs each. They make another model for those wanting RAID. Set up RAID, by all means, if squeeking every ounce of speed is your goal to be sure. My setup is conservative, redundant and very safe. A simple search here or on google for RAID0 or such will turn up much info on raid configuations.

Help my MAC OS X disc doesn't allow me to restore factory settings it just installs snow leopard and remains on my original user account?
You need to erase the disk first. From the 'Utilities' menu on the Install disk choose' Disk Utility; use this to erase the disk, then install the system plus (if it's the original install disk) any bundled applications.
I'm going to state the perfectly obvious just to be on the safe side: 'Erase disk' does exactly that - everything on the disk will be gone. -
Hi,
As the subject line says, I'm a Mac newbie. I've been on a PC for about 10 years and just got my mac last Friday (how time flies!), so I'm obviously completely unfamiliar with Macs and how to mess with them.
In any case, I've kept my PC for a couple of programs that I'd like to use and need my printer for one of them. I have my printer connected to my iMac and I've networked the two computers to transfer files back and forth. So my question is this: How do I set up my computers so that I can print through my iMac from my PC? I don't want to have to rearrange the entire office just to use the printer.
Any help would be great.
Thank you!Things to check -
1. Set your Mac to be in the same Workgroup as the PC. The PC's workgroup can be found by right clicking on My Computer, select tab Computer name.
On Tiger, you set the workgroup in the Utility Directory Access - I hope Kappy can tell you where to do that on Leopard.
2. Driver - once you can find the printer in the same workgroup, when you add the printer on the PC you will need to select a postscript driver - if the printer you're trying to use is postscript, fine, its driver will work. But if the printer is a typical inkjet, you need to select some other color postscript driver on the PC, because printer queues on Macs expect to receive postscript. The Apple Color LaserWriter xx driver included on my Windows XP works well.
Hope this helps. -
Mac osx freezes right after start up and all desktop files disappeared and the mouse can't click on anything..help?, Mac osx freezes right after start up and all desktop files disappeared and the mouse can't click on anything..help?
This is sometimes caused by Bad Blocks on the Hard Drive.
If 10.7, hold down Command-R at startup, and choose Disk Utility.
If 10.6 or earlier, boot to the Installer/Utilities DVD, answer only the "what language" question and wait for the MenuBar to be drawn. Choose Disk Utility from the Utilities Menu.
Select your Hard drive by Make & Model and check the SMART Status (lower right of the right window). Choose "Repair Disk" . This ONLY examines and repairs the Directory area of the drive, but may improve things a bit. If errors cannot be repaired, you may need a stronger tool, or a new drive. -
Need help for a newbie problem
I am VERY new to all this Java programming but have really started to enjoy it.
I have two problems with my program that I can not find answers to.
1. I am looking to find out why my code will not select the right answers when I select the first choice in the array. The answer that is delivered turns out to be the 3rd selection. The second and third selection work great, but the first selection always turns out with the thrid answer.
2. I know I need to do better error checking on the user input. At this point I am only checking for correct integer input, but I dont know how to fix or avoid the error for when the user would mistakedly enter letters instead of numbers.
Any hints?

Thanks for any help!When you choose Java to solve the problems, you need to adapt to the power/strategies/methodology that java offers you, and thats the way for solving problems in Java.
Why would you put the entire implementation for calculation inside main method? You could break down the program into smaller methods which could do the calculation bit and then call them in main method.
Anyways the reason that it is calculating for term of 7 years is that
// for statement loops last repayment option
for (rPay = 1; rPay <=3; rPay++)
{mPayment[lPay] = mPayment[lPay1++];
yTerm[rOller2] = yTerm[rOller3++];You are changing the value of the array yTerm[ ]. Hence once the control is out of the for loop the value of y[0]=7,y[1]=7 and y[2]=7.
Solution 1: mark yTerm as final.
Solution 2: set yTerm[0], yTerm[1] back as 30,15 after the for loop.
if (rOller1 <= 2)
// for statement loops last repayment option
for (rPay = 1; rPay <=3; rPay++)
{mPayment[lPay] = mPayment[lPay1++];
yTerm[rOller2] = yTerm[rOller3++];
mTerm[rOller] = mTerm[rOller1++];
iRate[liRate] = iRate[liRate1++];
//Output to screen for numerical repayment option info
System.out.println(" " + rPay + "\t $" + fappAmount + "\t\t " + yTerm[rOller2] + "\t" + mTerm[rOller] + "\t " + decimal.format(iRate[liRate]) + "% \t$" + decimal.format(mPayment[lPay])+ "\n\n");
yTerm [0]=30;
yTerm [1]=15;
}Futher the issue is with monthly calculation of pay back amount in switch - case statement.
As you have not provided what the problem is and what is the criteria for calculation of monthly interest or reducing the amount etc. Its not possible (at least for me) to tell you why it would run to negative. Mathematically that is the only thing possible,
Step 1: make those changes in your code. Make changes required to claculate the balance.
Step 2: Execute the new code and
Step 3: Gimme the dukes.

My computer worked fine last night, I got up this morniing, tried to log on and it was slow to take my password. I shut the computer off, restarted and it is stuck on the gray screen. If I shut the lid, the apple stays lit up. It will not charge my iPhone.
Does anyone have any advice before I have to take it somewhere to get it fixed? I'm a student, limited funds, and about 2 1/2 hours from an Apple store.
Thanks!

Please help my mac is so slow coming up and going to different places. the flower keeps coming up all the time?????
I'm having this problem but only online. I've confirmed that it is the computer (2007 MacBook), and it only happens when I'm using wi-fi connection. My other MacBook (2010) is connecting with wi-fi fine, and when I plug this MacBook into the ethernet connection it is also doing fine. I've re-started, check the memory, deleted cookies, histories, gone as far as uninstalling and re-installing browswers. Used the System Preferences network diagnostics and got an "all good". Ideas appreciated.
