My iPhoto icon has a cross over it, when i open it, it You have "iPhoto" 9.2.1. you can't use this with this version of OSX? it used to work ?what's gone wrong?

iPhoto 9.2.3 is incompatible with MacOS 10.9.3 Mavericks. If you are running Mavericks on your system you need to update iPhoto to 9.5.1. Only, the problem is, that this version is no longer available at the App Store.
The easiest way to get a compatible iPhoto version in that case would be to upgrade to Yosemite, MacOS X 10.10, and then download the most recent iPhoto version from the AppStore, iiPhoto 9.6, like LarryHN suggested.
If you cannot download iPhoto after upgrading to iPhoto 9.6 post back.

I'm trying to use a madcatz controller on the mac but it turns on for 2 seconds and turns off. the system profiler picks it up as a xbox 360 gamepad but says its not been configured. how can i allow my self use this with my games.

I have exactly the same problem.
I'm a little peed-off with Microsoft on this. The original wireless controller I have doesn't work either since the cable I'm using is 'just' the charge and play cable, so a direct connection to my Mac won't work with this cable. It's a cable for god's sake. Why on EARTH put any limitations on this!?!?
Next I learn I need an additional USB wireless receiver from Microsoft to get my original 360 controller to talk to my Mac. As I certainly don't want to fork any more microsoft dollars on this, this is not an option.
Next I think, yes! I have a MadCatz 360 wired USB controller. This should surely do the trick just plugging it in and the way I go. But oh no, for some reason I plug my MadCatz Xbox360 controller in, it flashes a few times then switches off and can't be turned on again.
The System Profiles recognizes it as a MadCatz 360 device controller but that is about it, but the ontroller software I download for the System Prefs (360Controller, USBOverdrive etc) don't even recognize the controller as being plugged in.
What the **** Is The Microsoft Deal with all of this!?!?
PS: Oh, and I forgot to mention, there are No drivers for device 4716 that I can find on the MadCatz website, or am I going blind?
If anyone has a link, it would be appreciated.

Your answer confused me for a second (a generic router doesn't need an adaptor for Macs to use) and then it dawned on me you were referring to the enet adaptor the MBA requires

My airport express works on my MBPro 17 w/ 10.5.8 but not my MBAir11". The MBAir says that this version of Airport utility doesn't support this base station. Is ther any chance I can use this with my MBAir?

Is this an older "round" version of the AirPort Extreme? If yes, it is true that AirPort Utility 6.x no longer supports the older AirPort Extreme and AirPort Express models.
A model number......located on the bottom of the Extreme or on the side of the Express would be helpful to confirm what you have.
Apple probably does want you to buy a new AirPort Extreme.
The workaround might be to use a Mac or PC running a 5.x version of AirPort Utility.
A more complicated workaround would be to install AirPort Utility 5.6 on Mountain Lion. This is not supported by Apple......it does work for me.....but may not work for you. See this article for more details:

BenQ XL2420T 120 HZ / 3D Ready - May I use this with my iMac?

Hi.
My Philips 190B monitor that I have been using with my iMac in Extended Desktop mode recently died so I'm looking for a replacement second monitor.
I also own a PS3. Well, actually I own two. One is sick at the moment.
I would like to replace the Philips with the new BenQ XL2420T monitor. Use it with my iMac as I did with the Philips (possibly for gaming too) and use it with one, or both, of my PS3s for gaming and 3D Blue Ray movies via HDMI. Thinking forward I am likely to get into 3D gaming too.
The BenQ has a 120Hz refresh rate and I wonder if the ATI Radeon HD2600 in my Mac can handle this? It's late 2007 vintage.
Or with the BenQ XL2420T monitor am I being too ambitious?
My Philips is currently connected to my iMac using DVI -D by means of an adapter.

Looks rather nice to be sure. It's got DVI-D so it ought to work with my iMac without a problem. My current monitor is (was) connected this way by means of a small adapter.
BenQ say it has it has HDMI 1.4 so it can work with consoles. Doesn't say 3D though, so I assume that is a 'no'. Strange that 3D should be omitted when all the consoles can handle this.
In fact I have just downloaded the extra info from BenQ ad the spec looks reallly impressive. I assume that D-Sub is what they call VGA now. I need VGA in case I ever bring my old PowerMac 6500/300 out of mothballs. Yes, the white Benq looks like a great second monitor for my iMac. I'm virtually certain now that it doesn't have 3D but now I'm not so sure about the desirability of having that facility. I'm intrigued by what they say about the 'Reading Mode'.
Thanks for the heads up, lottathings1. Really given me something to think about. LOL!

Bento software- can I use this with OS 10.4?

Someone suggested I try a software called Bento, but I've been checking the technical specs and it appears that I can't use it with OS 10.4. The minimum requirement is OS 10.5. Does anyone know if this is true? If so, can you recommend a similar software that I can use with OS 10.4?
Thanks!

Info Genie was a flat file database program as I recall. For something similar you might look at iData or iData Lite, Quick Tables (may not work on Tiger,) iList Data (relational,) EagleData. These are all pure database programs.
Notes Guru is a database program specifically for notes. If that's what you need then it may be fine for you. But if you have more generic needs or specialized needs please say what those are since it makes it easier to recommend something. Or you can simply search the MacUpdate and VersionTracker data for suitable choices you can download and try out.

I have a craft cd that can be used with a pc or Mac os-9. Can I use this with my snow leopard 10.6 ?

I have a craft cd that can be used with a pc or Mac 0s-9. Can I use this cd on my IMacG5 10.6.8?

Pop in the CD and try, however it is unlikely because Classic App's will not run in Snow Leopard.
Also note: that only 2006 Intel iMac's or later can run Snow Leopard and not per 2006 G5 iMac's.

ImpOSCar - Anybody using this with Logic pro 8

I'm thinking of buying impOSCar to use with Logic. Is anybody here using this software synth? Any problems with multiple instances of the plugin? bugs / crashes etc? Demo seems to work just fine but just wanted to check before handing over the cash.

One of my favourite softsynths.
Be sure to also pick up my (and other) extra patches from GForceSoftware.com...
Works great in Logic.
And as a bonus, it's one of the synths that's had it's internal parameter specifically mapped for the Logic Control, so all the parameters are arranged in groups of 8, with all the related parameters together (so one group of 8 is OSC parameters, another is filter params, another is envelope params etc). This makes it one of the few synths that can quite comfortably be tweaked via a Mackie Control or anything using the same MCU protocol, and is a really nice attention to detail thing from the GForce chaps.
Highly recommended.

How to use 'this' with synchronization?

Hi, I have the following program and the results are not synchronized as expected.
The TransThread class includes a synchronized block and a synchronized method. In my opinion, a non-static synchronized method will refer to 'this' as its objectidentifier so I use 'this' as the objectidentifier of synchronized block,too. But no synchronization happens. Would you like tell me why? Thank you in advance.
// SynTestDemo.java
class SynTestDemo
public static void main (String [] args)
FinTrans ft = new FinTrans ();
TransThread tt1 = new TransThread (ft, "Deposit Thread");
TransThread tt2 = new TransThread (ft, "Withdrawal Thread");
tt1.start ();
tt2.start ();
class FinTrans
public static String transName;
public static double amount;
class TransThread extends Thread
private FinTrans ft;
TransThread (FinTrans ft, String name)
super (name); // Save thread's name
this.ft = ft; // Save reference to financial transaction object
public synchronized void WithdrawOp()
ft.transName = "Withdrawal";
try
Thread.sleep ((int) (Math.random () * 1000));
catch (InterruptedException e)
ft.amount = 250.0;
System.out.println (ft.transName + " " + ft.amount);
public void run ()
for (int i = 0; i < 100; i++)
if (getName ().equals ("Deposit Thread"))
synchronized (this)
ft.transName = "Deposit";
try
Thread.sleep ((int) (Math.random () * 1000));
catch (InterruptedException e)
ft.amount = 2000.0;
System.out.println (ft.transName + " " + ft.amount);
else
WithdrawOp();

Thank you for your advice. I modified my code. But the outcome is incorrect if I use
if (thdName == "Deposit Thread")
the amount is always 100
while
the outcome is correct if I use
if (getName ().equals ("Deposit Thread"))
// SynTestDemo.java
class SynTestDemo
public static void main (String [] args)
FinTrans ft = new FinTrans ();
TransThread tt1 = new TransThread (ft, "Deposit Thread");
TransThread tt2 = new TransThread (ft, "Withdrawal Thread");
tt1.start ();
tt2.start ();
class FinTrans
public static String transName;
public static double amount;
public synchronized void update(String transName, double amount)
this.transName = transName;
this.amount = amount;
try
Thread.sleep ((int) (Math.random () * 1000));
catch (InterruptedException e)
System.out.println (transName + " " + amount);
class TransThread extends Thread
private FinTrans ft;
TransThread (FinTrans ft, String name)
super (name); // Save thread's name
this.ft = ft; // Save reference to financial transaction object
String thdName = getName();
public void run ()
for (int i = 0; i < 40; i++)
if (thdName == "Deposit Thread")
// if (getName ().equals ("Deposit Thread"))
ft.update(thdName,1000);

ft.update(thdName,100);

BT Hub 2.0 - Can I use this with different ISP?

I use TalkTalk as my ISP and have recently had a BT engineer call-out due to my very low BB speed. As my master socket is in the lounge dowstairs and I want the PC upstairs the BT man suggested I switch to wireless.
Bought the BT Hub 2.0 on recommendation, but have now read that it can only be used when BT is the ISP.
Is this correct and is there anyway around it?

The BT Homehub can only be used with BT Broadband, it is possible to "flash the firmware" to unlock it to other ISPs, but this is not really a simple task.
Why not contact talk talk and tell them you are thinking of leaving, I am sure they will do you a deal and send you a new wireless router, or you could always get one from that well known on line auction website.

Has anyone used this with Mavericks?

I have a Late 2013 iMac and was interested in this but not sure about other peoples use of it,
Mediasonic HF2-SU3S2 ProBox 4 Bay Hard Drive Enclosure with USB 3.0 & eSATA
Any input would be welcome. Thanks.

I posted on their forum also and see what members their say. I also asked the question on Amazon from previous buyers. There unit is a very reasonable price and does what I need, But I am not willing to take a chance with the disconnect problems some people are having. I had loads of problems with my four SATA 3 drives in external cases and hubs that were 3.0 USB. So far two hubs were on the shelf and a third plugable 7 port works fine.

Trying to use this() in a constructor, not the first line

I'm currently re-writing some old code of mine that was used to create a neural network. My main contructor, originally, was
public Network(int sizeLayer1, int sizeLayer2, int sizeLayer3) Now, however, I've decided that I want to make my network a little more general, and allow any number of layers. Therefore, my revised basic constructor is
public Network(int[] sizeLayers)which expects an array of ints corresponding to the size of each layer.
However, I've got some old programs that use the old contructor which I can't change (and anyway, it's good to have the option to be able to use both). I therefore want to create a constructor that has the same signature as the old one, but simply places the values in an array and passes the array to the new constructor.
public Network(int sizeLayer1, int sizeLayer2, int sizeLayer3) {
int[] sizeLayers = {sizeLayer1, sizeLayer2, sizeLayer3};
this(sizeLayers);
}obviously won't work, because 'this' must be the first line of the constructor. How can I put my values in an array and call the new constructor?
Thanks!

Silly me -- I had been trying to do
this({sizeLayer1, sizeLayer2, sizeLayer3});but of course that wouldn't work.
Thank you very much for that reply!
However, more generally, what if I wanted to do a few lines of processing on the variables passed, like adding them together before calling this()? Is there no way to do that? What's the purpose of requiring that this() be the first line in the constructor?
Thanks!
