Office and Mac Mini Solo Core

Hello.
I am having problems with my Mac Mini 1.5Ghz solo core with 512MB, and have 10.4.7 on my system. Office has always been a bit slow, obviously cos its running under rosetta. But I am having problems now when I click the application to open it doesnt open. I have to restart my machine each time just to try and open an excel document. It's weird cos sometimes it works and sometimes it doesn't. Is their any preferences files and other files I need to trash to get it to stop doing this and for my machine to run Office a bit more efficiently?
Thanks in advance for any help

I suggest you head toward the Microsoft Office:Mac forums found at http://www.microsoft.com/mac/community/community.aspx?pid=newsgroups
That group is dedicated to user questions about MS Office:Mac applications. You'll find more answers in that forum rather than an Apple forum dealing in Mac/Windows compatibility.

  • Hitachi PJ-TX300 projector and Mac Mini Intel Core 2 Duo?

    My PJ-TX300 projector is hooked up via its PC connector to my Mac Mini Intel Core 2 Duo, via a DVI to VGA adapter (which came with the Mini from Apple) plugged into the Mac mini. I cannot get a clear screen picture at any resolution: there is always ghosting. Can you advise me?

    Ghosting would typically implicate the video cable. Where did you get it? It sounds like you may have a very cheaply constructed VGA cable and a better one is needed.

  • Mac Mini Intel Core Solo 1,5GHz won't turn on

    Hi at all!
    I'm in a trouble with a Mac Mini Intel Core Solo-based.
    Well, when I connect power cord, after a while, Power LED self-turns on (without powering on the Mac), but Startup Chime isn't played, there aren't no video signals on screen, Optical Drive mechanics isn't initialized and no Hard disk Drive noise is audible.
    I can hear only (if I put my ear on Mini's body) a bit Fan Noise (and a bit air flow on the back).
    If I stay-pressing power button for 4 seconds, Mac turns off. It I re-press that button, Mac turns on again. Finally, if I long-press the power button, Mac DON'T perform PMU reset (with classical speed flashing of power led, Long beep and Startup Chime).
    What can I do to fix this problem?
    Thanks very much to all readers!

    You're right!
    I wrote PMU instead of SMU.....in fact, mine is an Intel-based Mac, and PMU is present only in PowerPC Architecture.... ^_^
    Sorry for my expression error.....:)
    While I'm writing..... I thought that, in my Self-repairing operations on the Mac Mini, I've also replaced the internal 3V battery (because, with a multimeter, I'd can verify that battery voltage was only 1,75V instead of near 3V). After that, I left Mac turned off for a certain interval of time (I was busy in other personal activities). So, when I turned on again the Mac (after the complete reassembly of the entire computer), the Startup chime was played and the Mac beguns to work.
    Is possible that, in the Mini - Intel Core Solo 1,5GHz, a low internal battery can cause problems like in the old dear iMacs G3 ????

  • Will logic pro x run on my mac mini dual core intel i5 with 4gb of ram and mountain lion ?

    hi there guys,
    will logic pro x run on my mac mini dual core intel i5 with 4gb of ram and mountain lion ?
    I'm not sure if my machine is 64 bit - it is the current model base mac mini.
    Many thanks for any help you can offer !
    Simon

    SkiJumptoes is right. 4GB is not enough to comfortably run Logic X.
    Your Mac Mini will need DDR3 SODIMM RAM. That website seems incredibly steep though. I guess that's the price of finding it for you. You're better off going to any below:

  • Mac mini Intel Core Duo fan very loud and runs at high speed all the time.

    I purchased an "Open box" Mac mini Intel Core Duo, 1.66Ghz, 2G ram, 80G HD and SD a few days ago from Fry's.
    It runs beautifully except the fan is very loud compared to any Mac my family has ever had. It is so loud that we were thinking of putting it under the desk.
    The fan runs constantly, and I mean all the time, at a high speed. You can really feel the air coming out the exhaust vents. The case is always cool to the touch as is the exhaust air.
    My aunt bought a similar Mac mini (But only 512Mb ram) the same day. Her's is very quiet. The case feels just slightly warm, not unlike other Mac mini's I've seen.
    Should my Mac mini's fan be running this way?
    Thanks,
    llulua
    BTW: The "open box" was sealed with a Fry's label and it said that this had a new warranty. Yet, checking the serial number, it said that it had about 260 days left. I guess Fry's is backing it?
    Also, someone told me that perhaps the main wire from the fan to the logic board is disconnected.

    Since you have 2 gigs of memory, my thoughts are that when the party (Fry's or the origianl purchaser) upgraded the memory, they neglected to reattach the wire at the front of the Mini under the IR receptor at the right front corner that regulates the fan speed. This wire must be unattached in order to upgrade the memory, and is probably why the original person brought it back, because of the fan noise resulting from failing to reattach the wire. If that wire is left unattached, the fan runs continually at high speed to protect the CPU and system in general. If you do not want to use a putty knife to open the Mini, take it back to Fry's and ask someone who is Mac savvy to open it and reattach the small plastic receptacle at the end of the wire into its socket at the right front of the machine. When I go to Fry's, I am always concerned because the employees allow people to pry keys off of the Apple notebooks, so don't expect that their employees to know or care about anything Mac.

  • Mac mini Intel Core Duo and HK Soundsticks USB, Any Problem???

    Hello everyone.
    I am thinking of "transferring" my "old" HK Soundsticks USB for my sis's new Mac mini Intel Core Duo.
    Is there any issue or problem with the mac detecting the USB speakers?? I thought I read somewhere here a while back that generally the Intel Macs might have a problem detecting the USB speakers.
    Thanks and cheers.

    Hi NewMoses, thanks for replying but you have to be specific, if you just bought your Soundsticks, it is most likely the HK Soundsticks II, is yours?? which has a normal audio jack, unlike the 1st Soundsticks, which has a USB input.
    I am sure the Soundsticks II with the audio jack would have not much problem on the new Intel Macs, since they are what I considered a "physical audio input", unlike the USB, which involves the USB technology, where more complication may come into play.
    Thanks and cheers

  • Mac mini Dual core vs. G4 500MHz Dual tower w/ non native applications

    I have a Power Mac G4, Dual 500MHz. I wanted to upgrade to the G5 tower, but am getting concerned that I will be buying an obsolete computer as Apple migrates to Intel. I use Microsoft Office and Adobe's Creative Suite 2 (CS2) primarily on my G4 and am really tired of the slow performance. I was thinking of buying the new Mac mini dual core and add an additional 7200 RPM external Hard Drive to improve the drive performance until the new Intel towers come out. I know that the applications I use are not written for the Intel processor. Does anyone know how well these applications perform on the Intel mini vs. my old old G4?

    In a year or so, there will probably still be more PPC Mac users than Intel ones, and I doubt that any smart company will end support for PPC Macs that early. Apple provided developers with a way to create Universal Binaires for two reasons : to avoid the confusion introduced by two versions (PPC & Intel) of the same app, and to force (i.e. strongly encourage) developers to support both platforms for quite some time.
    There's no doubt that a PowerMac G5 will run Leopard (Mac OS X 10.5), and probably the following version too. CS3 will be Universal, and will thus run at full speed on both PowerPC and Intel-based macs, and there's a chance that CS4 could be Universal too. If you buy a PowerMac now, it probably won't be outdated before three years or more.
    While the Intel Core Duo is much faster than a G4 and quite a bit faster than a single G5, I think that a Dual G5 could be about as fast as they are (maybe a bit slower "per-gigahertz", but Core Duos don't reach 2.3/2.5 Ghz yet anyway) ...
    Regarding the fact that Office runs well under Rosetta but not CS2, that's because CS2 is a much more demanding suite of applications, which probably features a lot of AltiVec code (software sepcifically optimized for the G4/G5's Velocity Engine - which wasn't originally supported by Rosetta and now is, but translating PPC code into Intel x86 isn't fast, so translating code that's supposed to run very close to the processor itself must cause an even grater performance loss). Even though Photoshop probably won't run slower than on your dual 500 Mhz, it probably won't run much faster, so if you don't want to get a PPC Mac, then I suggest that you keep your G4 for now and wait until Apple releases the next generation of PowerMacs.
    On the other hand, one of the reasons why your G4 is slow with Photoshop could be because you don't have enough RAM. Most people who have used the latest version consider that 512 MB is a minimum, and 1 or 2 GB are recommended. If you only have 256 MB or so in your Mac, why don't you just add some memory and wait until the next PowerMacs ?

  • Can not for the life of me get printing to work on my mac mini duo core

    I have a photosmart 7550 and laserjet 1012. And I can't get my mac mini to recognize either printer. This has been driving me nuts. I was a long time mac user in the 80s and early 90s. Switched to Windows. Just switched back with the mac mini (intel duo core). And I hate to say it, but it's just been an awful transition. My wife, which hates me that I made her get rid of her windows machine and switched it with this mini. If I don't get this mac printing I'm going to have to get rid of it.
    I've installed/reinstalled drivers from HP, removing the library/printer/hp directory. Guten-print. Nothing is working for me.
    Can anyone help me?
    mac mini duo core   Mac OS X (10.4.6)  

    If the printers are not being recognized by the Printer Setup Utility, it may mean that the printing services has not started up. You can check for this by using the Activity Monitor (/Applications/Utilities). Set it to show "All Processes", then click on the "Process Name" tab. That will sort the running processes in alphabetical order. Look for an entry for "cupsd". If you find no such entry, printing services is not running. You can probably turn it on by enabling Printer sharing (System Preferences-->Sharing).
    There should be a driver for the Laserjet 1012 that will be useable once you get the computer to recognize that there is a printer there. This according to the Apple article listing the drivers included with Intel Macs . Unfortunately, that article does not list a driver for the 7550. According to HP's support site, they do have drivers for Mac OS X 10.4. There is no entry, however, for the Intel Macs. I think you will have to wait for HP to release Intel drivers for the Photosmart printer.

  • Mac Mini Dual Core vs PowerMac DP G4

    I am considering purchasing a Mac Mini Dual Core to replace my PowerMac DP 1.25Ghz G4 . I'm worried whether I will be happy , and if it will be faster than my G4. The app's I run most are univeral binary or will be soon , so I'm thinking , yes. But I would feel more comfortable if I could get some solid input from some power Mac user's experienced or knowledgeable with the new Mac Mini
    PowerMac DP 1.25 Ghz , 1.5GB RAM   Mac OS X (10.4.5)   Dual 80GB Seagate Barracuda drives

    I can't imagine that an Intel Mac mini would ever be "faster" than a dual-processor G4 tower for most operations. The comparisons that Apple advertises, like "4X faster" are all against single-processor PowerPC Macs. Mac OS X does a good job at managing dual PowerPC processors.
    Although the new Intel Mac mini now has a faster system bus, you're MUCH more limited by the use of portable-size hard drives (for example, your PowerMac probably has over a 100GB drive to start with and could have 500GB without much cost). If you want to max-out the RAM on the new Intel Mac mini to 2GB, it will cost you $300 more. So, a 1.66GHz Core Duo Mac mini with a 120GB hard drive and 2GB of RAM is $1,224.00 (US). If I were you, I would, without question, keep the PowerMac and invest in a newer Super Drive and/or hard drive(s) before giving it up.

  • Dualdisc cd side won't play on my mac mini intel core duo w Superdrive

    Shakira Fijacion Oral DualDisc "CD" side will insert and then automatically reject from my Mac Mini - Intel Core Duo. The DVD side plays fine. Unfortunately iTunes not smart enough to work with DVD side. There is a query in IPOD forum about Springsteen DualDisc also failing on intel mini mac that is listed at "answered" but for the life of me, I can't tell if you are supposed to just not buy DualDisc or else take the Mac Mini back for a new drive.
    mac mini (intel core duo)   Mac OS X (10.4.7)   2GB RAM

    Mac Mini Intel Core Duo's did not ship until 2006 which seems plenty of time for Apple to announce 'we have a problem' and what their recommended solution.
    Why would they do that ? I mean, they don't have a problem. The inventors of DualDisc made a type of disc that won't play in all players, and Apple can't really do anything about it. Superdrives are not made by Apple, it's just Apple's name for a DVD burner; the Superdrives that are found in various Macs come from several different manufacturers, and although Apple probably ensures that the Superdrive and the Mac work well together, they won't test whether it works with each type of disc (usually, the manufacturer will).
    However, that is probably limited to redbook/standards-compliant discs; since a DualDisc's CD side doesn't comply with any standard other than "DualDisc", and because it is not considered important enough to be officially supported by most (if not all) manufacturers, they probably won't test them since they're bound to get mixed results anyway.
    Similarly I don't remember seeing a "strictly redbook only" disclaimer on any of the media available from Apple describing the capabilities of its Superdrive when I was making my mac mini buying decision.
    You didn't see one because it is not required. Asking that Apple (or any other company) warns you that their players won't play non-redbook CDs is a bit like asking that they tell you everything your optical drive won't play. Apple claims that their Superdrives will read CD-R/RW, DVD-R/RW, DVD+R/RW, DVD-R DL, which aren't only a bunch of weird-looking letters, but also correspond to a standard. When you see a CD logo on a drive, it means that it will play redbook-compliant CDs. Your Dell player simply does more that what it is supposedly capable of, but because one (or many) optical drives will play DualDisc doesn't mean that they all have to.

  • Mac mini intel core 2 duo 2.4ghz keeps freezing up

    I have a refurbished (bought from Apple) Mac Mini Intel Core 2 Duo 2.4GHz with upgraded 8GB of RAM, OS is latest Snow Leopard (10.6.8).  I have had this machine less than one year, and in the past five days it has started to freeze up quite often. 
    After running Disk Utility and getting a message that said to repair the disk, I hve run Disk Utility from the original disk to fix the problem.  No effect, I still have regular freezes and often.  I have run Disk Utility again several times, and have had to repair Permissions several times, though the Repair Disk says the hard drive is okay.  Only the Permissions keep getting messed up, and this happens quickly.
    I have no large number of video files on the desk top.
    I checked some threads and ran Activity Monitor and Control.  Control when I ran "disk0" did not show any problem.  I do not know how to interpret the Activity Monitor readings.
    Short of wiping the computer and reinstalling everything, is there a way to determine what is wrong with the computer?
    Thanks for any help!

    Hello,
    Only the Permissions keep getting messed up,
    You can ignore repeated Permission fixes if the last line says completed in it.
    See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
    http://support.apple.com/kb/PH7029
    Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
    How much RAM you have for real & free space do you have also, click on the Memory & Disk Usage Tabs.
    Open Console in Utilities & see if there are any clues or repeating messages when this happens.
    In the Memory tab of Activity Monitor, are there a lot of Pageouts?
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • Logitech headset Skype and Mac Mini Intel

    Hi,
    I own a Powerbook G4 and a new Mac Mini Intel Duo Core.
    Both machines run the same latest OSX version 10.4.6.
    On the Mac Mini I have a problem using Skype with my Logitech Headset 350 (usb). The system does recognize the headset, but for some reason the microphone of the headset is not working. The speakers work fine. I did set the prefrences right in the Skype menu.
    But on my Powerbook G4 the headset works perfectly fine.
    Could this be an Intel issue? Maybe I a driver (can't find one on the Logitech site)? Anyone any clue?
    Thanks, Fred

    On the Mac Mini I have a problem using Skype with my

    the headset is not working. The speakers work fine. I
    did set the prefrences right in the Skype menu.
    I have the same headset and it works fine. First, directly connect it to your mini, don't use the keyboard's USB hub since it can only drive 100mA devices. Second, check that the mic is actually on (the blue LED is constantly on, not flashing).
    If it still doesn't work go to System Preferences->Sound->Input then select the "USB Headset" and speak into the mic and watch the input level meter. If necessary adjust the "Input Volume".

  • Flash (is it for me?), Wacom Cintiq 22HD, and Mac Mini

    I have Flash as part of the CS6 Master Suite, which I purchased primarily for InDesign, Photoshop and Premiere, but as yet I haven't opened Flash. I'm hoping someone here can save me time by advising me whether Flash is suitable for my purposes. I'm not a professional, just a keen amateur, but I do want to use quality software and equipment to do the finest job I can.
    Answers to a previous post in the Illustrator forum (Re: Animation – is Illustrator what I should be using?) suggested that I try Flash.
    Background
    I'll be using Premiere for converting my audio-visuals to HD format. Back in the 1980s I was right into three-screen slide shows. As part of the transforming, I'll be introducing a small number of video clips (hence my need for Premiere) and also short animation sequences, probably 10 seconds at most. The animation will be done by an artist friend who is keen to extend his talents into computer art. If I buy the computer (some sort of Mac), a Cintiq, load the appropriate software, and then loan it all to Steve and show him how to use it, he'll happily spend as much time as required for the animation. We're bartering: he gets to use a computer and tablet for as long as he wants, I get animation.
    A typical animation might involve Steve drawing outlines at appropriate intervals, over a background, then having the software generate the in-betweens. Watercolour-style shading (i.e. not fill-type, monotone colour) would be added, probably manually for each frame, unless the tweening can competently handle watercolour-style shading. For some of Steve's doodlings on his iPad (simplified versions of what we're aiming for), check out http://www.mediafire.com/download/sj731c17co55g5w/Steve's_iPad_Work.zip
    We're both new to this and recently spent an afternoon together looking at videos on Flash and the Cintiq. The combination looks like it will work for us, but I have a few questions which I'm hoping some of the experts on this forum can answer. A simple yes or no may save me hours of reading documentation only to find out that something won't work as I want. I'll also include some questions about the Cintiq and Mac Mini in case someone who uses them with Flash can provide answers. I live in a place where I have no access to these devices before I buy. I have to buy 'cold'. Thus my wariness.
    Please note: I'm not an artist and Steve isn't computer literate. So some of these questions might appear pretty dumb to an experienced user of Flash/Cintiq.
    Ques 1
    Is Synfig Studio (as suggested at the end of my Illustrator thread) something I should consider? Or is Flash a better bet?
    Ques 2
    Does Flash have vector tools that mimic a watercolour paintbrush like in Photoshop? Or is that not possible as a vector, and such effects have to be done outside Flash and then imported as background (or other method)?
    Ques 3
    When a Flash animation is finished, how is it exported, for example, to Premier? Do you export as h.264?
    Ques 4
    It is not clear to Steve and I after viewing three Cintiq videos, how the Cintiq interfaces to Flash. Does the Cintiq know about Flash, and appropriates certain drawing tools automatically? Or do you have to tell Flash (or the Cintiq) that this button on the Cintiq now operates this tool in Flash?
    Ques 5
    Do Flash and Cintiq work well together – and easily?
    Ques 6
    Do I need a monitor to be able to use Flash with the Cintiq? Or would a Mac Mini be a suitable computer – with the Cintiq acting as monitor? Steve won't ever be using this setup as a computer. He'll be treating the Cintiq as a canvas on which to draw and paint.
    Thanks in advance for any replies.

    Hi Guy,
    I thought I was the only one around who was old enough to have worked on wide screen multi-image slide shows!
    Flash may be the right product for you and Steve. I use Flash with an Intuos 4 tablet and it works fine. What you want to do is to search the Flash forums for references to Cintiq. There may be some problems that interfere with your intended use, or it may work exactly as you want. The important element for working with any Wacom product is to be sure that you are using the latest drivers for the Wacom product.
    If you choose to use a mac mini, get a new one, one that can use a lot of memory, you'll need it.
    You can export Flash files to video in most any file type and compression is installed on the computer. So, if you're going to use a Mac, install Quicktime Pro and you should have everything that you need.
    I have never heard of or used Synfig Studio, so I can't comment on that.
    Flash's paint tools are different from Photoshop and more similar to Illustrator's. You will have all of the flexibility of the Cintiq to control painting effects, it will take some practice, but you should be able to get the effect that you're describing.
    Hope this helps with your decision.

  • How to connect a 23" Cinema display and mac mini to an AV Receiver?

    I am trying to get my 23" Cinema display and Mac Mini to a Yamaha RX-2700 AV Receiver. I am on first name terms with the guy in Maplins because I tried to get an Xbox 360 working with this display before and gave up in the end.  The AV receiver has upscaling capability so I thought I'd try again.  I tried connecting a HDMI - DVI adapter to the HDMI Out on the receiver and a HMDI to DVI cable from the Mac Mini to the HDMI in with a optical cable for the sound.  The sound works fine but I get no display - the LED on the monitor flashes three times with a blank screen so it can't read the signal.  Another option suggested was to use a VGA Converter connected to a VGA - HDMI cable but I would like to find out if that would work before going down that route?
    I am looking for some advice about whether this type of configuation is possible with the 23" ACD and if so what do I need to buy to make it work?  I love the quality of my ACD to avoid having to replace it with a TV to get my multi media life in order.
