Hi, likely somethiung else, but Free Sophos...
http://www.sophos.com/products/enterprise/endpoint/security-and-control/mac/
Very Important, how much Free Space is on your Hard Drive first of all? Click on the Macintosh HD on the Desktop, then do a Get Info on it.
First, Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
In the Memory tab, are there a lot of Pageouts?

  • What is the best data structure for loading an enterprise Power BI site?

    Hi folks, I'd sure appreciate some help here!
    I'm a kinda old-fashioned gal and a bit of a traditionalist, building enterprise data warehouses out of Analysis Service hypercubes with a whole raft of MDX for analytics.  Those puppies would sit up and beg when you asked them to deliver up goodies
    to SSRS or PowerView.
    But Power BI is a whole new game for me.  
    Should I be exposing each dimension and fact table in the relational data warehouse as a single Odata feed?  
    Should I be running Data Management Gateway and exposing each table in my RDW individually?
    Should I be flattening my stars and snowflakes and creating a very wide First Normal Form dataset with everything relating to each fact? 
    I guess my real question, folks, is what's the optimum way of exposing data to the Power BI cloud?  
    And my subsidiary question is this:  am I right in saying that all the data management, validation, cleansing, and regular ETTL processes are still required
    before the data is suitable to expose to Power BI?  
    Or, to put it another way, is it not the case that you need to have a clean and properly structured data warehouse
    before the data is ready to be massaged and presented by Power BI? 
    I'd sure value your thoughts and opinions,
    Cheers, Donna

    Dear All,
    My original question was: 
    what's the optimum way of exposing data to the Power BI cloud?
    Having spent the last month faffing about with Power BI – and reading about many people’s experiences using it – I think I can offer a few preliminary conclusions.
    Before I do that, though, let me summarise a few points:
    Melissa said “My initial thoughts:  I would expose each dim & fact as a separate OData feed” and went on to say “one of the hardest things . . . is
    the data modeling piece . . . I think we should try to expose the data in a way that'll help usability . . . which wouldn't be a wide, flat table ”.
    Greg said “data modeling is not a good thing to expose end users to . . . we've had better luck with is building out the data model, and teaching the users
    how to combine pre-built elements”
    I had commented “. . . end users and data modelling don't mix . . . self-service so
    far has been mostly a bust”.
    Here at Redwing, we give out a short White Paper on Business Intelligence Reporting.  It goes to clients and anyone else who wants one.  The heart
    of the Paper is the Reporting Pyramid, which states:  Business intelligence is all about the creation and delivery of actionable intelligence to the right audience at the right time
    For most of the audience, that means Corporate BI: pre-built reports delivered on a schedule.
    For most of the remaining audience, that means parameterised, drillable, and sliceable reporting available via the web, running the gamut from the dashboard to the details, available on
    demand.
    For the relatively few business analysts, that means the ability for business users to create their own semi-customised visual reports when required, to serve
    their audiences.
    For the very few high-power users, that means the ability to interrogate the data warehouse directly, extract the required data, and construct data mining models, spreadsheets and other
    intricate analyses as needed.
    On the subject of self-service, the Redwing view says:  Although many vendors want tot sell self-service reporting tools to the enterprise, the facts of the matter are these:
    v
    80%+ of all enterprise reporting requirement is satisfied by corporate BI . . . if it’s done right.
    v Very few staff members have the time, skills, or inclination to learn and employ self-service business intelligence in the course of their activities.
    I cannot just expose raw data and tell everyone to get on with it.  That way lies madness!
    I think that clean and well-structured data is a prerequisite for delivering business intelligence. 
    Assuming that data is properly integrated, historically accurate and non-volatile as well, then I've just described
    a data warehouse, which is the physical expression of the dimensional model.
    Therefore, exposing the presentation layer of the data warehouse is – in my opinion – the appropriate interface for self-service business intelligence.
    Of course, we can choose to expose perspectives as well, which is functionally identical to building and exposing subject data marts.
    That way, all calculations, KPIs, definitions, and even field names, and all consistent because they all come from the single source of the truth, and not from spreadmart hell.
    So my conclusion is that exposing the presentation layer of the properly modelled data warehouse is – in general - the way to expose data for self-service.
    That’s fine for the general case, but what about Power BI?  Well, it’s important to distinguish between new capabilities in Excel, and the ones in Office 365.
    I think that to all intents and purposes, we’re talking about exposing data through the Data Management Gateway and reading it via Power Query.
    The question boils down to what data structures should go down that pipe. 
    According to
    Create a Data Source and Enable OData Feed in Power BI Admin Center, the possibilities are tables and views.  I guess I could have repeating data in there, so it could be a flattened structure of the kind Melissa doesn’t like (and neither do I). 
    I could expose all the dims and all the facts . . . but that would mean essentially re-building the DW in the PowerPivot DM, and that would be just plain stoopid.  I mean, not a toy system, but a real one with scores of facts and maybe hundreds of dimensions?
    Fact is, I cannot for the life of me see what advantages DMG/PQ
    has over just telling corporate users to go directly to the Cube Perspective they want, that has already all the right calcs, KPIs, security, analytics, field names . . . and most importantly, is already modelled correctly!
    If I’m a real Power User, then I can use PQ on my desktop to pull mashup data from the world, along with all my on-prem data through my exposed Cube presentation layer, and PowerPivot the
    heck out of that to produce all the reporting I’d ever want.  It'd be a zillion times faster reading the data directly from the Cube instead of via the DMG, as well (I think Power BI performance sucks, actually).
    Of course, your enterprise might not
    have a DW, just a heterogeneous mass of dirty unstructured data.  If that’s the case,
    choosing Power BI data structures is the least of your problems!  :-)
    Cheers, Donna

  • What is the Best & Max Upgrade for Used Power Mac G5

    Hi All,
    I need your help on purchasing an old Second hand Power Mac G5, which will coast me nearly 1900$ with 20" Cinema Display? is this price is OK for the below Spec.:
    Processor: 2.0Ghz Dual Core (1MB Cache for single core)
    RAM: 512 MB, DDR SDRAM PCI 533.
    Graphic Card: Nvidia 6600 128
    Hard Disk: 160GB
    And Super Drive for the DVD Rom.
    As you see its have an old Graphic Card and Small amount of RAM so what is the best amount I can Add on RAM and Best Graphic Card to get the perfect performance?
    And What is the max size of the hard drive supported by the machine is it 2TB or less?
    And last not least can I install the new OSX (Leopard) on the machine and is there any difference between MAC Pro G5 and Power Mac G5?
    Looking forward for the answers and hopefully as soon as possible because I afraid somebody else will gonna by it, Thanks for the support and Good Bye.
    Thanks & Regards,

    Hi! It all depends on your use. If the machine is to be used for serious work such as video editing and Photoshop use then the more power you have usually means more productivity. On the other hand if you are just surfing the net and using word applications like Microsoft Office then nearly any machine is suitable. The early G5's could use 8 gigs of ram and the newer ones 16. Look HERE for late model specs and look HERE for slightly older models. For most people the fastest iMac is a hard machine to beat but there are tradeoffs with an all in one machine. If one component fails it's hard to repair but with a tower design such as a G5 or MacPro the components are easily more replaced. Also expandability with a tower is easier. You can multiple hard drives to a tower that you can't with an all-in-one machine. The new Macpros start at 2799 as per APPLE's SITE while the fastest iMac is 2199 as per APPLE's Site. I'm not a video card expert nor a raid expert so I'll leave those questions to others. Tom

  • I have a power pc (g5) computer that I will soon be replacing with a current i5 or i7 mini. How do I transfer the Time Machine files from the internal hard drive on the G5 to an external drive that I will later use with the Mini?

    Hi, likely the easiest is to just poll the drive & get something like this...
    Get MacScan...

    But if you have a good external drive already, just clone it.

  • What is the best way to use single shot drum sounds?

    I have a huge collection of wav. format single sound drum sounds that I use in FL Studio. What is the best way to program drums in GB using them besides buying iDrum? I like the flexibility of using drums from different kits when I make my music so I kind of get board using a preset drum kit from GB even layering 3-4 kits isn't as nice as choosing each individual drum sound.

    Would be great to have more info but on a 24fps timeline with 24fps footage, you can simply right click and change the speed/duration to whatever. It'll be more jittery than smooth 60fps slow-mo. If your footage is shot at 60fps and you are editing on a 24fps timeline, just select the clip and right-click and choose MODIFY>Interpret footage and change the fps to 23.976 and you're done. Now when you drop that clip on the timeline it's in smooth slow-mo. Or, you can just toss the original clip on the timeline and change the speed/duration setting to 40%. Pretty much the same thing although the former is better if you need to add any warp stabilization to the clip. Anything you want to speed back up you can either duplicate the clip in the project panel and change it back to the original frame rate OR you can simply adjust it on the timeline to 250% speed which is back to normal. Good luck!

    I think you should explain whether you're looking for an app to help you save the battery life of your iPhone, or an app to help you save power in your home or office. You've gotten recommendations for one of each thus far.

  • What is the best way to aggregate photos from multiple family users into a single iCloud photo library?

    My wife and I currently have a iPhone and iPad each.
    We share my apple ID account for apps and I also use this as my main icloud account on my devices.
    My wifes devices have a different main icloud account.
    We also have a iMac with separate users configures, which are tied to our individual icloud accounts.
    Now that OSX photos has been released we want to make use of it including icloud photo library.
    We take photos. Lots of them.
    And we want the photos from all our devices to be aggregated automatically into a single osx photos/iCloud photo library.
    1 - because we want a single library which includes all our photos from the last 15 yrs
    2 - because we don't want to pay twice for storage
    Seems to me there are two options - but I would be happy to hear any others.
    1) The family sharing route
    This seems to be the official solution, but it has major limitations.
    Set up family sharing. I'll be the organiser since its my apple id thats used for app purchases already
    Add my wife to the family
    Ah... but now she has to manually share every photo or moment from he device
    And it seems that these moments are not incorporated into the photos database in same way as the icloud library account users (me) are
    2) Family iCloud account
    I didn't test it yet, but no reason that I can see why it should not work
    Create a new icloud account for the family
    Make this family account the primary icloud account on all devices (could be a big disruption for icloud enabled apps)
    Add our personal apple ids as mail/contact/calendar account
    Make a new user on OSX for photos which has the family icloud account configured
    No all devices should share the same photo library
    Unfortunately:
    We lose bookmark, keychain, etc sync between devices and osx accounts
    We lose imessage (maybe).
    We lose the new ios8/yosemite features like handoff
    Or worse we get crazy imessage/handoff between all devices from all accounts
    Both methods have major downsides.
    Anyone know of a better way?
    Why doesnt apple allow multiple separate icloud accounts to be configured and select which features each can use (where some features may have to be unique to a single account). To me this would seem to be the best option...
