Skype lento nella digitazione? Ecco come risolvere

Ultimamente mi è capitato di dover fornire assistenza a persone che riscontravano una estrema lentezza nella (visualizzazione della) digitazione su Skype, specie nei casi in cui non si avesse a disposizione l’ultima versione di Mac OS X.
Anche l’installazione dell’ultima release del software VoIP più famoso del mondo, la 7.37 (178) al momento in cui scrivo, non ha aiutato nella risoluzione.

Una ricerca su Google e sui forum Skype mi ha fatto vedere come il problema si sia più volte ripresentato nel corso degli anni e su tutte le piattaforme per cui Skype ha offerto una versione del suo client. Le motivazioni di questo problema sono state le più disparate: un cambio dell’architettura di rete di Skype da P2P (come era nato) a classica client/server, ad una cattiva comunicazione con i sistemi di correzione ortografica offerta dal sistema operativo, a semplici bug o incompatibilità tra le varie librerie usate.

Nel mio caso specifico la strategia risolutiva è stata un downgrade del client Skype.

In primis mi sono assicurato di Disabilitare l’aggiornamento automatico dell’applicazione. Questo viene fatto andando a levare il segno di spunta alla voce “Mantieni skype sempre aggiornato” andando nel menù dell’applicazione Skype > preferenze > Generale.
Quindi si procede al download di una versione precedente del software, nel mio caso Skype 7.30.234.
Rimuovo la versione corrente dalla cartella Applicazioni (mantenendo tranquillamente i file di preferenze e impostazioni).
Installazione della nuova versione.

Così facendo il client ha ripreso a funzionare correttamente e senza alcun problema (sui Mac a disposizione, equipaggiati con OS X 10.9 ‘Mavericks’).
Buon lavoro a tutti!

Apple updates, late January 2016

During yesterday Apple has released a bunch of updates for its products. One minor update was made to iMovie which has reached the 10.1.1 release, solving some problems during YouTube sharing. But the most important ones are regarding: iOS 9.2.1, OS X 10.11.3 El Capitan, the browser Safari and the security update 2016-001.

I’ve successfully updated a bunch of Mavericks and El Capitan equipped Macs, alongside some iOS devices without any problem. So update trustfully!

Apple has made public some informations regarding those updates:

This time Apple has also made a Combo Update package available for OS X, permitting to upgrade an 11.11.0 installation without going through all the updates that took place since Sept. 30th 2015 … This package comes handy if you have to update a bunch of machines, and the download size gets up to 1.47 GB (circa 3x the size of a “live” update as I’ve seen so far). I suggest you using this to solve any ‘permission’ problem or other strange behavior of your Mac …

Also this time the download were at least twice as faster than I remembered, both at home and at work. It would be cool if also Apple would start a bittorrent-like update spreading strategy [like Microsoft has begun to implement with Windows 10 updates].

10 years ago … the coming of Intel, and me, to Apple computers

[10 anni fa] Dieci anni di Mac-Intel →

Yesterday my friend Domenico published a long and detailed article remembering the 10th anniversary of Apple abandoning PPC processor and embrace to Intel ones.

The same Intel and the same CPU they, for a long time, had mocked in their advertising.

In those days I was working as a teacher for CIFIR and had started my collaboration with an architecture & engineering studio in Bari, providing them tech support for hardware and software support, their integration in the studio’s LAN and improving their collaboration workflow.

I had some money spare, and was willing to finally learn also about OS X (in my university years or at home I never had the chance to do so). So when in mid. 2006 the – white – MacBook became available I made “the switch” too …

It was an amazing journey into a world of really good software design, were things worked almost automagically, and I kept asking myself why there weren’t more Apple on the streets and kept getting benefits of both commercial and open source software. OSS that most of the time was also better looking and performing than the Windows or GNU/Linux counterparts (Adium, Colloquy and Cyberduck were – and still are – the best example of this).

This year we are expecting something exciting in the CPU department from Apple, given the amazing performance’s results of the A9-X processor on the iPad Pro and the level of customization an miniaturization of the (retina) MacBook motherboard
