How is Logos4 running on the i7 macs? 

The different problems that I see on the forum is that due to slower mac machines?

I'm currently considering a laptop purchase and any input would be helpful.

I've got a 3 year old 24 inch iMac, version number is 8,1. Its got a 2.8 GHz Intel Core 2 Duo CPU, 6 GB RAM and a brand new 1 TB HDD with 64 MB cache (just installed it myself!).

When I run Logos 4 Mac on it, its workable but very slow on some things, like Passage Analysis. Buggy too, but I'm running the beta.

On the other hand, when I boot up Windows 7 in VMWare Fusion and run Logos, its as snappy and quick as can be. And I've only got 2 GB RAM allocated for my virtual machine. That's a beta too.

So the Logos 4 Windows is running awesome with lesser specs (on the same machine), but Logos 4 Mac is still kinda slow with much better specs.

Based on this, I might say that Logos 4 Mac needs some decent optimization done to it first, and a slower or older Mac isn't necessarily to blame.

With many hours using Logos 4 Mac on 2.8 GHz Quad Core i7 and 2.4 GHz Core 2 Duo iMac's, have experienced Logos 4 Mac being quicker on newer hardware (e.g. rebuild index took 2 hours on i7 vis 5 hours on Core 2 Duo).  Also, Logos 4 Mac menus appear faster on i7.

On Quad Core i7, personally found Logos 4 Mac more responsive than Logos 4 PC using Oracle's VirtualBox.  When using 64 bit Mac OS X kernel, running 64 bit Windows was noticeably faster than 32 bit Windows (e.g. 4 hours to rebuild index instead of 5 hours) with 2 CPU's allocated to virtual machine.  After indexing done, Logos 4 was quite usable in virtual machine (along with having more features).  Logos 4 Mac wiki page has Need Logos 4 PC feature? with configuration tips.  Thankful can use Logos 4 on Mac & PC.

Logos 4 is resource intensive on Mac & PC – benefits from fast processor, graphics, and disk along with adequate memory.  Currently, Solid State Disks (SSD) are faster than hard drives (no moving parts to position), but bit expensive.  Option: buy Mac with hard drive then upgrade to SSD and use original hard drive for Time Machine backups.

Logos 4 application is 32 bit (Mac OS X and Windows can use additional memory for file caching).  On Quad Core i7 had 16 GB RAM installed for 64 bit simultaneous use of Logos 4 Mac and PC versions (could sync between Mac & PC using Logos servers).  Wiki Slow Performance section includes monitoring memory usage (provided my incentive for 16 GB upgrade since 8 GB was not enough).

Some Logos 4 features are sluggish (e.g. wildcard search); slower computers take longer.

Thankful Greek Morphology visual filters are usable on older hardware (takes awhile to initially display) along with many Logos Bible Study features.

Watching Apple refurbished Mac's => http://store.apple.com/us/browse/home/specialdeals/mac have not seen 2011 MacBook Pro's (yet).  Anticipating older refurbished iMac's (including 1st generation i7's) to drop in price after iMac refresh.  After July 2010 refresh, 2.8 GHz Quad Core i7 iMac dropped from $ 1,899 to $ 1,699.
